Using the simple random sample of weights of women from a data​ set, we obtain these sample​ statistics: n=35 and x overbar =141.6lb. Research from other sources suggests that the population of weights of women has a standard deviation given by

a. Find the best point estimate of the mean weight of all women.

b. Find a 99​%
confidence interval estimate of the mean weight of all women.
