Question

In a linear regression model y = 2.4x + 11, where x represents the day and y represents the number of hits, predict the number of hits on day 15.

A. 36
B. -36
C. 47
D. -47

Answer 1

To predict the number of hits on day 15 using the linear regression model, substitute the value of x into the equation y = 2.4x + 11. The predicted number of hits on day 15 is 47 (option C).

Step-by-step explanation:

To predict the number of hits on day 15, we need to substitute the value of x into the regression equation y = 2.4x + 11. As x represents the day, we substitute 15 into the equation:

y = 2.4(15) + 11

Simplifying the equation:

y = 36 + 11 = 47

Therefore, the predicted number of hits on day 15 is 47 (option C).
