During one shift, the express lane clerk recorded how many times customers violated the "10 items or less" rule for his lane. In particular, he recorded how many items over the limit each violator placed on the conveyor belt. This data is summarized in the histogram below. NOTE: The last class actually represents "7 or more items," not just 7 items.

In a study conducted by some Statistics students, 73 people were randomly assigned to listen to rap music, music by Mozart, or no music while attempting to memorize objects pictured on a page. They were then asked to list all the objects they could remember. The summary statistics for each group are shown in the table. Complete parts a and b. HA: HM-HRU C. Ho: HM-HR <0 HA: HM-HR=0 ... Count Mean SD HA: HM-HRU D. Ho: HM-HR = 0 HA: HM-HR <0 Rap Mozart The 90% confidence interval for the negative difference in means is (.). (Round to three decimal places as needed.) 33 • 20 10.88 10.15. 3.71 3.04 No Music 20 13.29 4.88 Test the hypothesis. t = -0.78 (Round to two decimal places as needed.) P = 0.7799 (Round to four decimal places as needed.) State your conclusion. Use α = 0.05. Do not reject Ho. There is no evidence that the mean number of objects remembered by those who listen to Mozart is higher than the mean number of objects remembered by those who listen to rap music. b) Now compare…
