When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain about 160% of their maximum heart rate. For 20-year-olds, this rate is approximately 120 bpm. A simple random sample of one hundred 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. Based on the sample, the best point estimate for the population mean is bpm.
