###### Question details

Using the simple random sample of weights of women from a data set, we obtain these sample statistics:

nequals=40 and x overbarxequals148.51

lb. Research from other sources suggests that the population of weights of women has a standard deviation given by sigmaσequals=32.92 lb.
