→The number of sit-ups that all tenth-grade girls can do in 5 minutes is normally distributed.
→Beth surveyed 20 of her fellow intramural tennis players, all tenth-grade girls, and determined the mean number of sit-ups they could do.
I think she can't make an inference about the population mean for all tenth-grade girls based on the sample.The reason is that exact total population of class tenth girl is not given.
