Refer to Exercise 14.17 and the output given.
a. Identify the slope. Explain what it would mean if the slope were 0.
b. Test the hypothesis that the slope is 0 using the output. Show all the steps, and use a significance level of 0.05. The statistics for the test of the hypothesis that the slope is 0 can be found in the row labeled "MotherEd."
c. What would it mean if the slope were 1 and the intercept 0?
d. Test the hypothesis that the slope is 1 using a significance level of 0.05.
Use the table here to decide whether the p-value is less than 0.01, between 0.01 and 0.05, or more than 0.05 for part d.
