Question

When a movie is released to theaters, production companies monitor revenues from individual cities for that movie on its release date. Below is a scatter plot that shows 10 different movie revenues from opening night in both Tallahassee and Gainesville. Revenue is reported in millions of dollars.
Part B: According to the model found in Part A, if a movie brought in $32.2 million in total revenue in Tallahassee, what would the expected revenue be for Gainesville? (Round your answer to the nearest thousandths *three decimal places*)

Answer 1

Answer:

$13.299 million

Step-by-step explanation:

We need the model from Part A to answer Part B to three decimal places,

The point marked by the blue arrow is clearly an outlier. I ignored it in "eyeballing" the best-fit line.

My line has four points above and five points below the line,

You probably had to use a statistical calculator to get the equation for the line of best fit.

Assume it was

y = 38.9016 - 0.7951x

You would use that equation to predict y when x = 32.2.

y = 38.9016 - 0.7951 × 32.2 = 39.1588 - 25.6022 = 13.299

If a movie brought in $32.2 million on opening night in Tallahassee, it should bring in $13.299 million in Gainesville.
