The Regression Equation Suppose in this semester, our Exam 1 average was about 91 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 85 and a SD of 8.2. Use this information 1. What the slope of the regreso equation for predicting our Exam 2 scores from Exam 1 scores Round to 3 decimal places Tries 0/5
2. What the yntercept of the regression ecuation for predicting our team scores from Exam 1 scores found to 3 decimal places Tres 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 rounds to 29.) rest whole number. For example, 79.5 rounds to 80, n . But 79.49 Tres 0/5
4. Another student got a 65 on Fram 1. What would you predict her Exam 2 score to be? Round your answer to the nearest whole num
5. What is the SD of the prediction errors (same as RMSE) of our regression ecuation Round to 2 decimal places.
