In a random sample of 47 high-school students enrolled in SAT test training, it was determined that the mean amount of money spent per student was $110.96 per class with a sample standard deviation of $8.30. Construct and interpret a 95% confidence interval for the population mean amount spent per student for an SAT class.

A) ($108.52, $113.40); We are 95% confident that the population mean amount spent per student for a single SAT class is between $108.52 and $113.40.

B) ($108.52, $113.40); There is a 95% chance that a randomly selected student will spend between $108.52 and $113.40 for a single SAT class.

C) ($108.59, $113.33); We are 95% confident that the population mean amount spent per Student for a single SAT class is between $108.59 and $113.33

D) ($108.59, $113.33); There is a 95% chance that a randomly selected student will spend between $108.59 and $113.33 for a single SAT class.
