Your grandmother claims that the baby boomer generation is thriftier than the millennials and that boomers save more money with coupons than millennials. In order to test this 17 millennials and 12 boomers agreed to track how much money they saved in a month by using coupons at the grocery store. At the end of the month, the mean savings for the boomers was $26.97 with a standard deviation of $14.60, whereas the millennials saved an average of $18.09 with a standard deviation of $3.48. Perform an appropriate hypothesis test to test the null hypothesis that the true mean savings for boomers and millennials are equal versus the alternative that they are different. What is the test statistic and p-value of this test? Test statistic = 2.066; p-value = 0.061 %3D Test statistic = 2.066; p-value = 0.969 Test statistic =-2.066; p-value 0.031 %3D Test statistic=-2.066; p-value =0.939 %3D
