Answer 1

Solution: The regression equation given is:

$y=-0.414x+106.55$

Where:

y is the percent of people in an audience who finish watching a documentary

x is the length of the film

We have to find the percent of people in an audience who will finish watching a documentary that is 95 minutes long.

Using the above regression equation, we have:

$y=-0.414x+106.55$

        $=-0.414 \times 95 + 106.55$

        $=-39.33 + 106.55$

        $=67.22 \approx 67\%$

Therefore, the correct answer is option A. 67%
