We wish to estimate the average number of heart beats per minute for a certain population. The average number of heart beats per minute for a sample of 49 subjects was found to be 90. Assume that these 49 patients constitute a random sample, and that the population is normally distributed with a standard deviation of 10. Construct 90 percent confidence interval for the mean heart beats.
