Question Description
Complete the following problems using R and/or MS Excel. Be sure to show your work and include the hypothesis tests, the critical values, the computed test values, and the resulting decisions where applicable.Section 13-2
Perform these steps:State the hypotheses and identify the claim.
Find the critical value(s).
Compute the test value.
Make the decision.
Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified. Assume all assumptions are met.Game Attendance An athletic director suggests the median number for the paid attendance at 20 local football games is 3000. The data for a random sample are shown. At ? = 0.05, is there enough evidence to reject the claim? If you were printing the programs for the games, would you use this figure as a guide?

Lottery Ticket Sales A lottery outlet owner hypothesizes that she sells 200 lottery tickets a day. She randomly sampled 40 days and found that on 15 days she sold fewer than 200 tickets. At ? = 0.05, is there sufficient evidence to conclude that the median is below 200 tickets?
Section 13-3
Use the Wilcoxon rank sum test. Assume that the samples are independent. Also perform each of these steps.State the hypotheses and identify the claim.
Find the critical value.
Compute the test value.
Make the decision.
Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified. Assume all assumptions are valid.Lengths of Prison Sentences A random sample of men and women in prison was asked to give the length of sentence each received for a certain type of crime. At ? = 0.05, test the claim that there is no difference in the sentence received by each gender. The data (in months) are shown here.
