1. Explain the difference in use and computation between the z test
and the t test.
2. Test the following hypothesis using the t test: Researchers are
interested in whether the pulses of long-distance runners differ from
those of other athletes. They suspect that the runners' pulses will
be slower. They obtain a random sample (N = 8) of long-distance
runners, measure their resting pulses, and obtain the following data:
45, 42, 64, 54, 58, 49, 47, 55 beats per minute. The average resting
pulse of athletes in the general population is 60 beats per minute.
