A study of women’s weights found that a randomly selected sample of 300 women had a mean weight of 150 lb. Assuming that the population standard deviation is 18.2 lb., construct a 95% confidence interval estimate of the mean weight of all women. Choose the correct interval from below: (147.294, 152.706)

(147.940, 152.060)

(147.904, 152.060)

(147.915, 152.085)
