 H0: β = 0 There is no evidence of a linear relationship between number of classes and GPA.HA: β ≠ 0 There is evidence of a linear relationship between number of classes and GPA.The conditions for inference have been met.t = -2.56; df = 18; p-value = 0.0195; α = 0.05With a p-value of 1.95% < 5%, I reject H0. We have statistically significantly evidence that there is a linear relationship between number of classes and GPA.
