for the following set of scores: (a) Find the regression equation for predicting Y from X. Show your work.(b) Calculate Ŷ (aka "Y‐hat", or the "predicted Y") for each of the five values of X. Hint: one of these Ŷ values will be 1.75.(c) What proportion of the variance is accounted for by the regression equation? Show your work.(d) Does the regression equation account for a statistically significant portion of the variance? Assume that α = 0.05, and show your work. The final F statistic will be 6.804 if you keep three decimal places of precision.
