Question description
The data on the Question 3 gives the height (in inches) of 20 males and 20 females as well as the heights of their mother and father. Your task is to determine whether you can predict the height of males using their father’s height and whether you can predict the height of females using their mother’s height.a. Ace my homework – Write the null and alternative hypotheses for these situations.b. What is/are the dependent variable(s)?c. What is/are the independent variable(s)?d. Run a regression analysis for each situation.e. Ace my homework – Write each regression equation to predict height from respective parent’s height.f. What is the correlation coefficient for the men?g. What is the correlation coefficient for the women?h. What percent of variability of the dependent variable in men can be explained by the regression?i. What percent of variability of the dependent variable in women can be explained by the regression?j. Do you accept or reject the null hypotheses? Why or why not?k. If a father’s height is 72 inches, what would you predict his daughter’s height to be based on the regression data generated?l. If a mother’s height is 63 inches, what would you predict their daughter’s height to be? m. If a father’s height is 72 inches, what would you predict his son’s height to be?
