When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain about 60% 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.
a) Test the following hypotheses at 5% significance level - follow the five steps.
b) Construct a 95% confidence interval for the population mean weight control heart rate for 20-year-olds and give an interpretation for the calculated confidence interval.
c) Do you think if we changed the confidence level to be 99%, the confidence interval would be wider or narrower? And why?
