**Transcription for Educational Website:**---You are interested in finding a 90% confidence interval for the average commute that non-residential students have to their college. The data below show the number of commute miles for 15 randomly selected non-residential college students. Round answers to 3 decimal places where possible.\[ 10, \, 22, \, 27, \, 16, \, 7, \, 15, \, 9, \, 6, \, 10, \, 24, \, 6, \, 9, \, 19, \, 26, \, 20 \]a. To compute the confidence interval use a \_\_\_\_ distribution.b. With 90% confidence the population mean commute for non-residential college students is between \_\_\_\_ and \_\_\_\_ miles.c. If many groups of 15 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About \_\_\_\_ percent of these confidence intervals will contain the true population mean number of commute miles and about \_\_\_\_ percent will not contain the true population mean number of commute miles.---**Explanation:**This section introduces the concept of confidence intervals and asks students to calculate the interval for the average commute distance of non-residential college students using sample data. Specific distribution details and percentage calculations are to be filled out to complete the assignment.

Empathy among police officers influences how they interact with citizens and the likelihood that they receive complaints. Gender differences in levels of empathy in the general population are not large but male and female officers have been shown to have different interaction styles with the public; this may be due to the different empathy levels. After sampling officers and measuring their levels of empathy you find the following data. Males Females n = 6 n = 9 M = 31 M = 45 SS = 490 SS = 680 If you were going to make gender comparisons like this, which option would be the correct choice? Write A or B in the box. [a] Option A. Independent-measures t-test Option B. Repeated-measures t-test
