To find the equation of the line of best fit and the correlation coefficient, you can use a graphing calculator or a statistical software.
Using a graphing calculator, input the data points and perform a linear regression analysis.
The equation of the line of best fit is usually represented as:
y = a * x + b
In this case, the equation would be:
y = 20.67x - 40029.24
The correlation coefficient, represented as r, indicates the strength and direction of the relationship between the variables. In this case, the correlation coefficient is given as r = 0.992.
To predict the number of movie tickets sold in 2014, substitute the year 2014 into the equation:
y = 20.67 * 2014 - 40029.24
Simplifying the equation gives:
y ≈ 41678
Therefore, the predicted number of movie tickets sold in 2014 is approximately 41678 million.
