Access the answers to hundreds of Normal distribution questions that are explained in a way that's easy for you to understand. The answers to part f and part g are close, because a normal distribution is an excellent approximation when the sample size is greater than 30. 2^{\circ}$ F, and that body temperatures had a standard deviation of $0. 7^{\circ}$ F. The approximation would have been less accurate, because the smaller sample size means that the data does not fit normal curve as well.
