A university conducted a study of whether running is healthy for men and women over age 50. During the first eight years of the study, 1.1% of the 458 members of a fitness association died. We are interested in the proportion of people over 50 who ran and died in the same eight-year period.
NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
Which distribution should you use for this problem? (Round your answers to four decimal places.)

A study is being conducted to determine whether drivers at or over the age of 70 have longer reaction times in a simple driving task than drivers aged less than 70. A SRS of 50 drivers at or over age 70, and another SRS of 60 drivers under age 70 is selected. Each driver’s reaction time to a specific driving activity was measured in a laboratory, and the reaction times in minutes were recorded. The sample mean and sample standard...

Suppose a study was done to determine if the mean work week has increased. 68 women were surveyed with the following results. The sample mean was 83;...
