A sample of 16 students was taken from LIU university. These students spent an average of $170 on books this semester, with a standard deviation of $25.50. A 98% confidence interval for the average spent on books for all students would be: [B]* O [153.41 186.59] O [171.45-178.55] O [156.50 -183.50] O [158.82-181.18]
