Statistics Project
The data below represents the number of hits on your web site over 10 months.Make a scatter plot of ln y versus x. Use the scatter plot to find the equation for the line of best fit.Make a scatter plot of ln y versus ln x. Use the scatter plot to find the equation for the line of best fit.Based on your answers in part a and b, would an exponential model or a power model be better to represent this data? Explain.Use your answers from parts a and b to find an exponential model and a power model to represent this data by hand.Use the regression feature on your calculator to find an exponential model and a power model to represent this data.Use your answer from parts c and d to make the best estimate for the number of hits your web site will have in 12 months

Relationship of Height and Weight, statistics homework help
Relationship of Height and WeightUsing the given Height and Weight data set, follow the steps in the weekly video or on pages 584-585 of the textbook for performing a regression analysis using Excel to analyze the Height and Weight Data set (assume height is the input variable x and weight is the output variable y).Once you have performed the analysis in Excel, state the correct simple linear regression equation and use the regression equation to predict the weight (in pounds) of a person who is 65 inches tall and the weight (in pounds) of a person who is 100 inches tall.Why might the regression equation you have found not be a good predication of the weight of someone who is 100 inches tall?

queueing theory
i have 3 questionsQ1 The post office uses a multiple channel queue, where customers wait in a single line for the first available window. If the average service time is 1 minute and the arrival rate is 7 customers every five minutes, using the Queuing.xlsx calculator tool, find, when two service windows are open, a. the probability both windows are idle. b. the average number of customers waiting in line. c. the average time a customer is in line. d. the average time a customer is in the post office. Q2 Circle Electric Supply is considering opening a second service counter to better serve the electrical contractor customers. The arrival rate is 10 per hour. The service rate is 14 per hour. If the cost of waiting is $30 and the cost of each service counter is $22 per hour, then should the second counter be opened? Q3 A company has tool cribs where workmen draw parts. Two men have applied for the position of distributing parts to the workmen. George Fuller is fresh out of trade school and expects a $6 per hour salary. His average service time is 4 minutes. John Cox is a veteran who expects $12 per hour. His average service time is 2 minutes. A workman's time is figured at $10 per hour. Workmen arrive to draw parts at an average rate of 12 per hour. a. What is the average waiting time a workman would spend in the system under each applicant? b. Which applicant should be hired?

Stratford University Importance of Measures of Center and Variation Discussion
A. Welcome to the final project. Introduce your scenario and data set.Provide a brief overview of the scenario you are given above and the data set that you will be analyzing.Classify the variables in your data set.Which variables are quantitative/qualitative?Which variables are discrete/continuous?Describe the level of measurement for each variable included in your data set.Discuss the importance of the Measures of Center and the Measures of Variation.What are the measures of center and why are they important?What are the measures of variation and why are they important?Calculate the measures of center and measures of variation. Interpret your results in context of the selected topic.MeanMedianModeMidrangeRangeVarianceStandard DeviationDiscuss the importance of constructing confidence intervals for the population mean.What are confidence intervals?What is a point estimate?What is the best point estimate for the population mean? Explain.Why do we need confidence intervals?Based on your selected topic, evaluate the following:Find the best point estimate of the population mean.Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown.Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.Write a statement that correctly interprets the confidence interval in context of your selected topic.Based on your selected topic, evaluate the following:Find the best point estimate of the population mean.Construct a 99% confidence interval for the population mean.

Explain.What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain.Discuss the process for hypothesis testing.Discuss the 8 steps of hypothesis testing?When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?Perform the hypothesis test.If you selected Option 1:Original Claim: The average salary for all jobs in Georgia is less than $65,000.Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.If you selected Option 2:Original Claim: The average age of all patients admitted to the hospital with infectious diseases is less than 65 years of age.Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.Based on your selected topic, answer the following:Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.Is the test two-tailed, left-tailed, or right-tailed? Explain.Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic?

Texas A & M International University Chi-Square Test for Independence Questions
Question 1:A researcher is interested in knowing if there are differences between the incidence of accidents among (1) employees who received only video safety training and (2) employees who received hands-on safety training.They were able to collect 102 responses from a random number of employees. Among them, 27 video-only employees were in accidents, 36 were not; 23 hands-on training were in accidents, 16 were not. Construct a contingency table. Run the Chi-Square test for independence using the calculator in the Module. State your findings and their significance. Do not forget to give summary statistics in APA format.Question 2:A researcher has found that pilots taking an over the counter antihistamine have poor reaction times. They performed an experiment on 22 pilots: 11 took the medication and 11 did not. Their reaction times to a command by Air Traffic Control was considered to be adequate or inadequate. Among those taking the medication, 9 were rated inadequate and 2 adequate. Among those not taking the medication, 10 were rated adequate and only 1 inadequate. Construct a contingency table. Run the Chi-Square test for independence using the calculator in the module. Construct a contingency table.•State your findings and their significance. Do not forget to give summary statistics in APA format.•What is the problem with this research study? Is the Chi-Square test appropriate? Why or why not? What could the researcher do to potentially rectify the problem?
