Asked Oct 23, 2019

The table shows data collected on the relationship between the average daily temperature and time spent watching television. The line of best fit for the data is yˆ=−0.66x+88.5. Assume the line of best fit is significant and there is a strong linear relationship between the variables.

 Temperature (Degrees)    Minutes Watching Television 

   35                                        66

   45                                        58

   55                                        52

   65                                         46

 

(a) According to the line of best fit, what would be the predicted number of minutes spent watching television for an average daily temperature of 46 degrees? Round your answer to two decimal places, as needed.

Step 1

Given data

Line of ...

Line of best fit
y-0.66x 88.5
According to the line of best fit, predicted number of minutes spent watching television for an
average daily temperature of 46 degrees is given by
Putting the value ox x= 46 in the line of best fit
y = -0.66 x 46 +88.5 = 58.14
