T = beta_1/sigma/squareroot SXX = squareroot n - 2 r_xy/squareroot 1 - r^2_xy Heights of mothers and daughters (Data file: Heights) Compute the regression of dheight on mheight, and report the estimates, their standard errors, the value of the coefficient of determination, and the estimate of variance. Write a sentence or two that summarizes the results of these computations. Obtain a 99% confidence interval for beta_1, from the data. Obtain a prediction and 99% prediction interval for a daughter whose mother is 64 inches tall. Average prediction error (Data file: Heights)
