| 24 of 24 (12 complete) This Test: 24 pts possil Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a icant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The number of hours 6 students spent ours spent studying, x 1 Find the regression equation Then use the regression equation to predict the val for a test and their scores on that test are shown below (a) x = 3 hours (c)x 12 hours (b) x = 4 5 hours (d)x 35 hours 41 47 51 63 y- (Round the slope to three decimal places as needed.

Explanation / Answer

y = 4.722x+39.17

Option C is Correct

a) y = 4.722*3+39.17 = 53.3

Option C is Correct

b) y = 4.722*4.5+39.17 = 60.4

Option A is Correct
