WEEK 6 ACTIVITY - SAMPLING DISTRIBUTIONSampling DistributionA computer scanner can read a bar code on a package correctly 97% of the time. One company monitors the accuracy of the scanner by randomly sampling packages and verifying that each package has been correctly scanned. Random samples of size n = 25, 50, 100, and 200 have recently been taken with the following results.Sample Size, n Number Correctly Scanned 25 2450 49100 95200 193To complete this activity, use Excel to:Calculate the sample proportion for each sample size. Calculate the single-proportion sampling error for each sample size. Calculate the probability of finding 198 correctly scanned packages, for a sample of size n=200. Submit your work Excel file.WEEK 7 ACTIVITY - HYPOTHESIS TESTINGHypothesis TestingThe Lazer Company has a contract to produce a part for Boeing Corporation that must have an average diameter of 6 inches and a standard deviation of 0.10 inch. The Lazer Company has developed a process that will meet the specifications with respect to the standard deviation, but it is still trying to meet the mean specifications. A test run (considered a random sample) of parts was produced, and the company wishes to determine whether this latest process that produced the sample will produce parts meeting the requirement of an average diameter equal to 6 inches. Use Excel to:Construct the appropriate null and alternative hypotheses with correct parameters. Develop the decision rule assuming that the sample size is 200 parts and the significance level is 0.01.In a Word document:Recommend what the Lazer Company should conclude if the sample mean diameter for the 200 parts is 6.03 inches.Submit your recommendations in a Word document and attach your Excel file.

Probabilities of Graduation and Publication, statistics homework help
Instructions In the following study, three different universities have been tracking a select group of professors over the course of their employment at that university to determine the number of students who are in a particular professor’s classes, how many of those students have graduated, and if any of them have had their work published. In the attached Excel file, Probabilities (attached below), are the totals for each of the professors at the three different universities that participated in the study.The purpose of this study is to find the probabilities of graduation and publication for the students in the different professors’ courses. While a causal relationship may not be found between a professor and student graduation or publication, we need to rank the professors based on the different probabilities found with the data sets as described below.Prepare a report (see below) with your ranking of the professors based on the probabilities and conditional probabilities as well as the analysis of each university. Include the following seven (7) items in table format which is provided in the Probabilities file to support your ranking.Note: Be sure to use five (5) decimal places for your probabilities in the table, as some of them will be quite small. Do not convert to percentages as we are interested in probabilities only here.The overall probability of students graduating at each of the three universities.The overall probability of students having a publication at each of the three universities.The overall probability of students having a publication, given that they graduated at each of the three universities.The probability of a student graduating for each professor.The probability of a student having a publication for each professor.The probability of a student having a publication given that they graduated for each professor.Rank the professors within each university for each of the probabilities in 4–6. Then find the sum of the ranks and determine an overall ranking for each professor.Be sure to critically analyze the above calculations in your body paragraphs, explaining how you found each type of probability and then the results you obtained. Be sure to also explain your criteria for ranking in steps 4–7, and defend why you chose that ranking method—as your way might not be the typical method.Paper Requirements Write a report that uses the Written Assignment Requirements under the heading Expectations for CSU-Global Written Assignments found in the CSU-Global Guide to Writing and APA. Items that should be included, but are not limited Items that should be included, at a minimum, are a title page, an introduction, a body which answers the questions posed in the problem, and a conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. As with all written assignments, you should have in-text citations and a reference page. Please include any tables of calculations, calculated values, and graphs associated with this problem in the body of your assignment response.Note: You must submit your Excel file with your report. This will aid in grading with partial credit if errors are found in the report.

Capella University T test Analysis & Application Research Paper
Instructions Complete the following for this assignment: You will complete this assignment using the Data Analysis and Application template (DAA Template [DOC]).Refer to IBM SPSS Step-by-Step Guide: t Tests [DOC] for additional information on using SPSS for this assignment.If necessary, review the Copy/Export Output Instructions [HTML]
to refresh your memory on how to perform these tasks. Your submission
should be in narrative format with supporting statistical output (table
and graphs) integrated into the narrative in the appropriate places (not
all at the end of the document).As you work on this assignment, you may find the Data Set Instructions [DOC] helpful. You will analyze the correlations among the following variables in the grades.sav data set: gender.gpa. Step 1: Write Section 1 of the DAA: The Data Analysis Plan. Briefly describe the goal of your analysis.State your research question, null, and alternate hypothesis.Specify the variables used in this analysis (predictor, outcome) and the scale of measurement of each variable.State the sample size (N) and the alpha level you will use (.05 unless otherwise specified).Explain why the analysis is a good choice based on the nature of your variables. Step 2: Write Section 2 of the DAA: Testing Assumptions. Articulate and test the assumptions of the t test.Paste the SPSS histogram output for each variable and discuss your visual interpretations.Paste SPSS descriptives output showing skewness and kurtosis values and interpret them.Paste the SPSS descriptives output showing skewness and kurtosis values for gpa and interpret them.Paste the SPSS output for the Shapiro-Wilk test of gpa and interpret it.Report the results of the Levene test and interpret it.Analyze whether the assumptions of the t test are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions. Step 3: Write Section 3 of the DAA: Results and Interpretation. Paste the SPSS output of the t test. Include the following:
t.Degrees of freedom.p value.Effect size.Interpretation of effect size.Means and standard deviations for each group.Mean difference.95% confidence interval of the difference of sample means. Interpret statistical results against the null hypothesis and state whether it is accepted or rejected. Step 4: Write Section 4 of the DAA: Statistical Conclusions. Provide a brief summary of your analysis and the conclusions drawn.Analyze the limitations of the statistical test.Provide any possible alternate explanations for the findings and potential areas for future exploration. Step 5: Write Section 5 of the DAA: Application. Analyze how you might use this statistical approach in your field and what the potential implications would be.Readings Read about how to apply your knowledge of t tests and run some analyses in SPSS.
