The data below are the nal exam scores of 10 randomly selected history students and the number of hours they slept the night before the exam. Find the equation of the regression line for the given data. What would be the predicted score for a history student who slept 7 hours the previous night? Round your answer to the nearest whole number. Use the following values to speed up the calculations: 5c = 4.2, E x = 42, Z x2 = 208, SSxy = 165.4, 37 = 76.8 \"In-"u m\":- 0 3) = 35.5x -55.33; Y(4.2) = 93.8 0 3/ = 5.234x + 54.82; Y(7) = 91.5 0 3) = 0.198x + 56.11; Y(7) = 57.5 0 3} = -5.044x + 56.11; Y(7) = 20.8 0 3) = 5.234x + 54.82; Y(4.2) = 76.8 0 None of these
