Question

The table shows data collected on the relationship between the time spent studying per day and the time spent reading per day. The line of best fit for the data is yˆ=0.16x+36.2. Assume the line of best fit is significant and there is a strong linear relationship between the variables.

• According to the line of best fit, what would be the predicted number of minutes spent reading for someone who spent 67minutes studying? Round your answer to two decimal places.
