A study of women’s weights found that a randomly selected sample of 150 women had a mean weight of 147.3 lb. Assuming that the population standard deviation is 19.6 lb., construct a 95% confidence interval estimate of the mean weight of all women. Choose the correct interval from below: Choose one • 10 points (144.211, 150.389) (140.611, 146.789) (144.667, 149.933) (144.163, 150.437)
