Question

Following are the data on total hours studied over 2 weeks and test score at the end of the 2 weeks from Exercise.
a. At the 1% significance level, do the data provide sufficient evidence to conclude that a negative linear correlation exists between study time and test score for beginning calculus students?
b. Repeat part (a) using a 5% significance level.
Presuming that the assumptions for regression inferences are met, perform the required correlation t-tests, using either the critical-value approach or the P-value approach.
