7) A random sample of 16 apples taken from the same orchard are measured for their weights. The sample had a mean weight of 86 grams and a standard deviation of 17 grams. Find the 90% confidence interval for the mean weight of all apples in the orchard. You may assume the weights of the apples in this orchard are normally distributed. You must write an interpretation. 8) A college admissions office is trying to determine if there is a linear correlation between a student's high school grade point average and the grade point average the student earns during his or her first year in college. A sample of 12 students is taken, yielding the following Highschool GPA: 2.4, 2.5, 2.8, 2.9, 3.1, 4.0, 3.3, 3.0, 3.4, 3.2, 3.9, 3.8 College GPA: 2.6, 1.9, 2.7, 2.5, 2.4, 4.0, 2.9, 2.7, 3.1, 3.0, 3.3, 3.2 Conduct a hypothesis test to test for a linear correlation between high school GPA and first-year college GPA. Use 0.05 as the significance. level. Report the p-value and write an interpretation
