The table shows data collected on the relationship between time spent playing video games and time spent with family. The line of best fit for the data is ŷ = -0.36x + 94.5. Assume the line of best fit is significant and there is a strong linear relationship between the variables. Video Games (Minutes) Time with Family (Minutes) 40 80 55 75 70 69 85 64 (a) According to the line of best fit, what would be the predicted number of minutes spent with family for someone who spent 36 minutes playing video games? Round your answer to two decimal places.
