Use the following description to answer question 9. The mean height of American women in their early twenties is about 64.5 inches and the SD is about 2.5 inches. The mean height of men the same age is about 68.5 inches, with a SD about 2.7 inches. It is also known that the correlation between the heights of husbands and wives is about r = +.50. Women (Y) Men (X) 66 70 64 68 62 66 66 71 65 67 67 68 62 69 66 69 65 69 63 67 68 70

9. Use Excel to obtain the values for the following (A) What is the value of the slope for the regression equation when predicting women’s heights from men’s heights? (B) Obtain the value of the y intercept. (C) Provide an interpretation of the y intercept obtained in part B. (D) Create a scatterplot for the data above and plot the regression line. (E) What are the predicted heights for wives whose husbands’ heights are: 70, 69, and 67?
