# Question

A random sample of 29 community college students were asked their height in inches and the height of their biological parent of the same gender. The output of a regression analysis for predicting student height from parent height is shown. Assume that all the conditions required are fulfilled, and use a significance level of 0.05 for any tests.

a. What is the slope of the regression line? Interpret the value of the slope in context.

b. Test the hypothesis that the slope is 0 (significance level is 0.05), and explain what your answer means.

c. If the slope were 1, what would that say about the association?

d. Test the hypothesis that the slope is 1 using a significance level of 0.05. Use the table for Exercise 14.18 to decide whether the p-value is less than 0.05. The degrees of freedom (df) is 27.
