Now that we have our linear regression model, let’s try to make a prediction for the sales given a new set of advertising budgets as follows: new. dat <- data. frame(TV=200, Radio=10, Newspaper=20) You are required to report the predicted sales as well as the lower and upper bound for the 95% prediction interval. What will you report?

The predicted sales for the new set of advertising budgets is 14.

Step-by-step explanation:

The linear regression model is:

Compute the value of sales for:

TV = 200,

Radio = 10,

Newspaper = 20

Thus, the predicted sales for the new set of advertising budgets is 14.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
