Suppose you are given the following information about five Math 1 150 students from a past semester (x is how many semesters the student has been at BenU, and y is how many classes the student has taken at BenU): x 1 2 3 5 8 y 3 8 11 20 26 6. (3 pts) Find the correlation coefficient xy. 7. (1 pt) Find the least-squares regression line. 8. (1 pt) Suppose a Math 1150 student has been at BenU for 6 semesters. Use the least-squares regression line to predict how many classes this student has taken. 9. (1 pt) What is the accuracy of the predicted number of classes? 10. (1 pt EC) Change two values of y in the table given above to get perfect linear cor- relation
