CRITICAL THINKING CHECK 8.3 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.
