Jennifer, a college student, would like to make the claim that the average amount that students spend on textbooks each semester is more than $225. Jennifer samples 16 of her classmates and obtains a sample mean of $244. At the 2.5% significance level, should Jennifer reject or fail to reject the null hypothesis given the sample data below? • Ho : µ= $225; H : µ > $225 0.025 (significance level) • test statistic = 2.51 a = Use the graph below to select the type of test (left-, right, or two-tailed). Then set the a and the test statistic to determine the p-value. Use the results to determine whether to reject or fail to reject the null hypothesis.

Select the correct answer below:
O Do not reject the null hypothesis because the p-value 0.006 is less than the significance level a = 0.025.
O Reject the null hypothesis because the p-value 0.006 is less than the significance level a = 0.025.
O Reject the null hypothesis because 2.51 > 0.025.
O Do not reject the null hypothesis because 2.51 > 0.025.
