Use the Teams data frame from the LahmanRbroom package. Fit a multivariate linear regression model to obtain the effects of BB and HR on Runs () in 1971. Use the tidy() function in the package to obtain the results in a data frame.1) What is the estimate for the effect of BB on runs? What is the estimate for the effect of HR on runs?2) Fit a linear model on the results from Question to determine the effect of year on the impact of BB. For each additional year, by what value does the impact of BB on runs change?3) What is the p-value for this effect?
