Using the data from the class survey, I ran the following regression: Y = a + bx, where Y represents the number of times a student exercises per week, and X represents the number of times a student goes to the beach. The output from this regression is below. Source Model | Residual 92.4688387 338.273429 Total I 430.742268 exerciseti~s | beach cons SS Coef. --- (e) p-value (f) What do you conclude?
