3. Chapter 16, Data Set 2, 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 (Time) and the number of guesses it took to get each item correct (Correct). Time Correct 14.50 5 13.40 7 12.70 16.40 21.00 624 13.90 3 17.30 12 12.50 5 16.70 4 22.70 3 a. What is the regression equation for predicting response time from number correct? b. What is the predicted response time if the number correct is 8? c. What is the difference between the predicted and the actual number correct for each of the predicted response times?
