A Statistics professor wants to estimate the mean Math SAT score of incoming freshmen. It is known that Math SAT scores are normally distributed. In a random sample of 20 incoming freshmen, the mean Math SAT score was 527 with a standard deviation of 88. Construct a 90% confidence interval for the population mean. Use the appropriate formulas and show your work! 6.__________________________[8]
