Using the simple random sample of weights of women from a data set, we obtain these sample statistics: n=50 and x-bar =150.09 lbs. Research from other sources suggest that the population of weights of women has a standard deviation given by o=30.83lbs. a) Find the best point estimate of the mean weight of all women. b) Find a 95% confidence interval estimate of the mean weight of all womena) The best point estimate is .b) The 90% confidence interval estimate is lbs< mu <lbs.
