Explanation & Answer
f(x) = 5x + 7
f(a ) = 5a + 7
f (a + h ) = 5(a + h ) + 7 = 5a + 5h + 7
( f ( a + h ) - f (a ) ) / h
( 5a + 5h + 7 - 5a + 7 ) / h
( 5a - 5a + 5h + 7 + 7 ) / h
( 5h + 14 ) / h

Math 160 CC American Chiropractic Association Discussion
Learn by DoingHere are the directions, grading rubric, and definition of high-quality feedback for the Learn by Doing discussion board exercises. ContextStudents researching backpack weights gathered data from 45 elementary school children in the 3rd and 5th grades. The variable is “percent of body weight carried in the school backpack.” So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 ÷ 60 = 0.15 = 15%). The American Chiropractic Association (ACA) recommends that children carry no more than 10% of their body weight.PromptWhen we analyze backpack weight as a percentage of body weight, how do 3rd and 5th graders compare? Are children in this study following the ACA recommendation?% of body weight carried in backpackThirdgradersFifthgraders 0-5%11 5-10%66 10-15%114 15-20%37 20-25%01 25-30%02 30-35%01Totals2122Note: Left-hand end-points are included in each bin. So the 2nd bin contains students carrying 5% of their body weight.

Exercise 26
Exercise 261. Plot the frequency distribution for “Age at Enrollment” by hand or by using SPSS. 2. How would you characterize the skewness of the distribution in Question 1—positively skewed, negatively skewed, or approximately normal? Provide a rationale for your answer. 3. Compare the original skewness statistic and Shapiro-Wilk statistic with those of the smaller dataset ( n = 15) for the variable “Age at First Arrest.” How did the statistics change, and how would you explain these differences? 4. Plot the frequency distribution for “Years of Education” by hand or by using SPSS. 5. How would you characterize the kurtosis of the distribution in Question 4—leptokurtic, mesokur-tic, or platykurtic? Provide a rationale for your answer. 6. What is the skewness statistic for “Age at Enrollment”? How would you characterize the magnitude of the skewness statistic for “Age at Enrollment”? 7. What is the kurtosis statistic for “Years of Education”? How would you characterize the magnitude of the kurtosis statistic for “Years of Education”? 8. Using SPSS, compute the Shapiro-Wilk statistic for “Number of Times Fired from Job.” What would you conclude from the results? 9. In the SPSS output table titled “Tests of Normality,” the Shapiro-Wilk statistic is reported along with the Kolmogorov-Smirnov statistic. Why is the Kolmogorov-Smirnov statistic inappropriate to report for these example data? 10. How would you explain the skewness statistic for a particular frequency distribution being low and the Shapiro-Wilk statistic still being significant at p < 0.05?

Northeastern Business Problem Overview and Analytics Based Solution Assignment
The broader signature assessment assignment calls for the development of an analytics program as a change agent in a new business venture. In this assignment, you will be introduced to the first phase of that assessment and the associated analytics program which requires you to establish a clear understanding of the business problem you wish to address. You are required to provide an overview of the program objectives and requirements from a business perspective. You will then connect this knowledge to a high-level data mining problem definition.To complete this assignment please:Provide a one paragraph overview of a business problem you would like to addressList three objectives, from a business perspective that an analytics-based solution would addressList three requirements, from a leadership perspective that will lead to a successful analytics-based solutionProvide a one paragraph summary connecting the business problem to a possible data mining solutionPlease note that this assignment should be no longer than the equivalent of one double spaced page. You must be succinct. Please refer to the attached paper for assistance in developing a problem statement.

Statistics Worksheet
Your research team has been tasked with finding the correlation of the following scenario: Four research participants take a test of manual dexterity (high scores mean better dexterity) and an anxiety test (high scores mean more anxiety). The scores are as follows: Person Dexterity Anxiety 1 1 10 2 1 8 3 2 4 4 4 -2 Describe the process your research team would go through by completing the following: Create a scatter diagram of the scores, which should be a negative direction. Describe in words the general pattern of correlation, if any. Figure the correlation coefficient. Explain the logic of what you have done, writing as if you are speaking to someone who has never heard of correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing). Provide three logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation in light of the variables involved. Explain why.

BADM 7020 LSU Mod 4 ABC Company Factors & Parameter Estimates for 4 Biggest Factors Paper
Module 4 AssignmentIn this assignment, you will apply what you've learned in this module about the designs of experiments to a sample data set and scenario.Assignment InstructionsConsider the following: The ABC Company wants to optimize the response (click rate) to their online ads. After a brainstorming session, thirteen factors were identified as potentially having an effect on the response (click) rate. The table below lists the 13 factors and the two levels that should be considered. This data is available in the DOE Assignment JMP file attached below.

How many treatments do you need at a minimum to estimate 13 main effects and the overall mean? Find a design using JMP DOE>Classical Designs>Screening Designs add 13 factors and find a design.What is the minimum number of treatments (runs)?What is the fractional factorial design with the smallest number of runs you can use for our problem?Which other design could you choose?2. Once you have a design matrix you would carry out the treatments and collect the response for each treatment (run). To exercise the analysis of a design I provided you with a 20 run design (which is the Packett-Burman design shown ion your list) which has responses provided in the JMP file. Use the design matrix provided in the DOE_Assignment_5_Click(2).jmp file with the number of clicks as the response variable. Use DOE>Classical>Two Level Screening> Fit Two Level Screening . Which factors are statistically significant at p<=0.05? Highlight the statistically significant factor rows (use individual p) and click run model. Interpret the output.
3. To evaluate the current design matrix with just the few main factors you determined to be significant, use DOE>Design Diagnostics>Evaluate Design. Select only the statistically significant factors for the evaluation. Look at the Alias Matrix to see what the problems are with using the same 20 runs to estimate the interaction effects (confounding of main effects and interaction effects). Specifically, we are interested in the 2-factor interaction between the biggest effects. What main factors are confounded with this interaction and what is the magnitude? Interpret the finding. (Note: find the column of the 2-factor interaction which had the largest effect. Then see what row has a number different from zero and what the main effect in that row is. The larger the absolute value the larger is the confounding. )4. Now we want to evaluate the data based on our discovery that the 2-factor interaction is confounded with another important factor. Go back to the open window you had before (DOE>Classical>Two Level Screening> Fit Two Level Screening ) and select the statistically significant factors plus the 2-factor interaction of the two biggest effects. Click Run Model again. Interpret the output. What is likely happening?5. Make a final selection on the window (DOE>Classical>Two Level Screening> Fit Two Level Screening) of what you think is the true likely factors and or interactions. Then click Run Model again. Interpret final model. Prepare the report using the following formatting guidelines:1 page, single-spaced report using 0.5 margins and two-column format1 page for appendixInclude title of report, then FirstName, LastName, ISDS course #, Assignment #, date (00/00/00)10 pt Font Calibri or Times New RomanJustified as sample reportCreate headings for each sectionList any references used (e.g. Module 1 Resources)Include a title for your report e.g. "Text Analysis of Workers Compensation Claims" and create headings for each sectionInclude supporting relevant figures from the analysis in your AppendixSubmit as pdf with filename first name initial last name and assignment number (for instance HSchneider#1)Be sure to review the Assignment Rubric and Assignment Example attached below.
