Question

3. The regression equation y = –0.414x + 106.55 approximates the percent of people in an audience who finish watching a documentary, y, given the length of the film in minutes, 70 x.

Answer 1

The answer is 78%

Explanation:

Step 1: The given regression equation y = -0.414x + 106.55

Step 2: The length of the film = 70 minutes

Step 3: Plug in x = 70 in the given equation and find the value of y.

y = -0.414 (70) + 106.55

y = -28.98 + 106.55

y = 77.57

Y = 78%
