In a genetic inheritance study discussed by Margolin, blood was collected from samples of individuals from several ethnic groups, and mean sister chromatid exchange (MSCE) was measured for each individual. We wish to see if there's a difference in average MSCE for the groups labeled "Native American" and "Caucasian." Here's the data: Native American: 8.50, 9.48, 8.65, 8.16, 8.83, 7.76, 8.63 Caucasian: 8.27, 8.20, 8.25, 8.14, 9.00, 8.10, 7.20, 8.32, 7.70 a. What's the experimental unit? What measurements are taken...

2. Two ride-sharing companies, A and B, provide service for a certain city. A random sample of 52 trips made by Company A and a random sample of 52 trips made by Company B were selected, and the number of miles traveled for each trip was recorded. The difference between the sample means for the two companies (A−B) was used to construct the 95 percent confidence interval (1.86,2.15). Which of the following is a correct interpretation of the interval? A....

A consumer group was interested in comparing the operating time of cordless toothbrushes manufactured by two different companies. Group members took a random sample of 18 toothbrushes from Company A and 15 from Company B. Each was charged overnight and the number of hours of use before needing to be recharged was recorded. Company A toothbrushes operated for an average of 117.7 hours with a standard deviation of 1.74 hours; Company B toothbrushes operated for an average of 120.6 hours...
