The table below shows the temperature in degrees for eight consecutive days as well as the respective number of ice cream cones
cricket20 [7]

Answer:

We have to find the equation of least squares regression line in order to find the number of ice cream cones that the shopkeeper to sell if the temperature is 106 degrees. We can use excel regression data analysis tool to find the equation of the regression line. The excel output is attached here.

The equation of the least squares regression line is:

\hat{y}=46.587+5.080x

Now, if the temperature is 106 degrees, then the number of cones expected to be sold is given below:

\hat{y}=46.587+5.080 \times 106

         =585.1 \approx 585

Therefore, the number of ice cream cones that the shopkeeper would expect to sell if the temperature is 106 degrees is 585.
