An October 1-10, 2019, Gallup poll asked 1,526 U.S. adults how much they planned to personally spend on Christmas gifts this year. The report cited an average of $942.

(I've already answered 5 and need help with Question 8)

8. Suppose the women reported planning to spend an average of $942 with standard deviation $150. Compare the margin of error of this interval (Hint: 2SD) to that in #5. Was your prediction correct? 5. Suppose s was equal to $150. Use the 2SD method (Hint: Reminder to consider the SD of the sample mean) to approximate and interpret a 95% confidence interval for u. (Hint: You are 95% confident that what is between what two values?) Based on my answers, we are 95% confident that population mean is between is between 1,226 and 1,826. M = 1,526, s = 150
