A hypоthesis test is dоne tо determine if there is а lineаr correlаtion between the number of hours a student studies (x) and their grade in a class (y). The linear correlation coefficient is 0.029. A random sample of 8 students were studied and the normalcy conditions were met. The regression equation was y = 2x + 42, for a study time of 0 to 27 hours, where students studied a mean of 11 hours with a standard deviation of 3.5 hours and the mean score on the exam was 64. What is the best predicted grade for a student that studies for 8.5 hours?
