Question
The registrar office of a small college isinterested in predicting the freshman GPA scores from high schoolGPA. They hire a student to work on the project. He tests the nullthe slope of regression line for predicting freshman GPA scoresfrom freshman GPA is zero and he also calculates the 95% CI for theslope.He writes:
High school GPA is a significant predictor of freshman GPA (t = 12,P = 0.000) and as high school GPA increases by one unit college GPAincreases by 0.70 units. He reports the 95% CI for the slope to be(-1.2 to +1.3).
Would you hire this student again?
Choose one answer. A. Yes, I would. Hewas right in rejecting the null becasue the p value is lessthan0.05. B. Yes, I would hedid the test of the slope and reported the t and the pvalues. C. No, I would notbecasue he does not provide us with the value for the standarderror of the slope. D. No, I would notbecasue based on the P value he is rejecting the null and based onthe CI he is not.

Explanation / Answer
Answer: D. No, I would not because based on the P valuehe is rejecting the null and based on the CI he is not.
