Chapter 16 Data Set 1 contains the data for a group of participants who took a timed test. The data are the average amount of time the participants took on each item (Response Time) and the number of guesses it took to get each item correct (Number Correct).

a. What is the regression equation for predicting Response Time from Number Correct? Use the SLOPE and INTERCEPT functions to create the equation.

b. What is the predicted Response Time if the Number Correct is 8?

c. What is the difference between the predicted and the actual Response Time for each of the Number Correct scores?
