Transcribed Image Text: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 significant 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 for a test and their scores on that test are shown below.
