Question

The data below are the final exam scores of 10 randomly selected Algebra students and the number of hours they studied the week prior to the exam. Find the equation of the regression line for the given data. What would be the predicted score for a student who studied 5 hours the previous week? Round your answer to the nearest whole number. Use the following values to speed up the calculations: x? = 4.8, ?x = 48, ?x^2 = 300, SSxy = 233.6, y? = 77.3 Hours, x | 3 | 5 | 2 | 9 | 2 | 4 | 4 | 10 | 6 | 3 Scores, y | 65 | 80 | 60 | 88 | 66 | 78 | 85 | 90 | 90 | 71 None of these y? = 0.198x + 56.11; Y(5) = 91 y? = 3.356x + 61.19; Y(5) = 80 y? = 3.356x + 61.19; Y(5) = 78 y? = -5.044x + 56.11; Y(5) = 31 y? = 3.581x + 55.33; Y(5) = 73
