To find the equation of the line of best fit and the value of correlation coefficient r, we can use a graphing calculator. The equation of the line of best fit is ŷ = -355.19 + 7.39x and the correlation coefficient is r = 0.9121. To predict the number of movie tickets sold in 2014, substitute x = 24 into the equation and solve for ŷ. The predicted number of movie tickets sold in 2014 would be approximately 177 tickets.
To find the equation of the line of best fit and the value of correlation coefficient r, we can use a graphing calculator. Using the given data points, we can input them into the calculator and perform linear regression. The equation of the line of best fit is ŷ = -355.19 + 7.39x and the correlation coefficient is r = 0.9121.
To predict the number of movie tickets sold in 2014 (x = 24), we can substitute the value of x into the equation and solve for ŷ. So, ŷ = -355.19 + 7.39(24) = 177.45. Therefore, the predicted number of movie tickets sold in 2014 would be approximately 177 tickets.
