In a survey, 48 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $68 and standard deviation of $15. Calculate, state, and interpret a 95% confidence interval to estimate the mean amount of money parents spend on their child's birthday gift. Round to the nearest 100th where necessary.
