The following summary statistics are obtained from a sample of n = 342 pairs of mother and daughter. Average SD Mother's Height (in inches) 58 3.6 Daughter's Height (in inches) 70 2.3 The correlation between the mother's height and daughter's height is r=0.52. Using linear regression, predict the height (in inches) of a daughter whose mother is 53-inch tall. Make sure your answer contains at least three digits after the decimal point Daugther's Height: number (rtol=0.01, atol=1e-08)
