Assignment:
Height and Weight Shown below are select Minitab results obtained using the heights in inches) and weights (in lb) of 40 randomly selected males (based on Data Set in Appendix).
Pearson correlation of HT and UT = 0.522
P-Value = 0.001
The regression equation is UT = -139 + 4.55 HT
a. Determine whether there is sufficient evidence to support a claim of a linear correlation between heights and weights of males.
b. What percentage of the variation in weights of males can be explained by the linear correlation between height and weight?
c. Letting y represent weights of males and letting x represent heights of males, identify the regression equation.
d. Find the best predicted weight of a male who is 72 in. tall.
