RY * 4.33 Height and Armspan for Women (Example 4) TI-84 output from a linear model for predicting armspan (in centimeters) from height (in inches) is given in the figure. Summary statistics are also provided. NORMAL FLOAT AUTO REAL RADIAN MP n LinReg y=a+bx a=16. 80271378 b=2. 249707146 r2=. 8987441215 r=. 9480211609 Mean Standard Deviation Height, x 63.59 3.41 Armspan, y 159.86 8.10 To do parts a-c, assume that the association between armspan and height is linear. a. Report the regression equation, using the words "Height" and "Armspan," not x and y, employing the output given. Sy b. Verify the slope by using the formula b = r-. c. Verify the y-intercept using a = y - bx. d. Using the regression equation, predict the armspan (in centimeters) for someone 64 inches tall
