Independent random samples of students who eat blueberries and those who don't at a uni versity yielded the following grade point averages (GPA). Assume that the GPA of blueberry and nonblueberry students are Gaussiandistributed. Students sample size average grade point sample variance Ne Blueberries 0-185 _- om We would like to determine if this evidence supports the claim that the mean GPA for students who don't eat blueberries is lower than the mean GPA for those who do. (a) Clearly identify the null hypothesis and alternative hypothesis. (1)) Select an appropriate test statistic, and calculate the pvalue of this test. (c) Is the test result signicant at the 1% signicance level
