The Regression Equation Suppose in this semester, our Exam 1 average was about 92 with an SD of about 10.5. Suppose the correlation between our Exam 1 and Exam 2 scores will be similar to what it has been in the past, about 0.75, and finally, suppose our Exam 2 scores will be similar to previous semesters' Exam 2 scores with an average of 86 and a SD of 8.2. Use this information to answer the following questions: 1. What is the slope of the regression equation for predicting our Exam 2 scores from Exam 1 scores? Round to 3 decimal places. Tries 0/5 2. What is the y-intercept of the regression equation for predicting our Exam 2 scores from Exam 1 scores? Round to 3 decimal places. Tries 0/5 3. A student got a 96 on our Exam 1. Use the regression equation you just calculated to predict her Exam 2 score. ( Round to the nearest whole number. For example, 79.5 rounds to 80, not 79, but 79.49 rounds to 79.) Tries 1/5
