Question
When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain
approximately 60% of his or her maximum heart rate. For 20-year-olds, this rate is approximately 120
bpm. A simple random sample of thirty 20-year-olds was taken, and the sample mean was found to be
107 bpm, with a standard deviation of 45 bpm. Researchers wonder if this is evidence to conclude
that the expected level is actually lower than 120 bpm.
Compute the p-value:
O 0.023
O 0.062
O 0.002
O 0.02
