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 significantcorrelation.) Then use the regression equation to predict the value of y for each of the givenx-values, if meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below.

(d) x=2.5 hours

Find the regression equation.

y= x+( )

(Round the slope to three decimal places as needed. Round they-intercept to two decimal places asneeded.)
