Solution 1

To estimate y when x = 25 using the regression model y = 63.3 + .51x, you simply substitute x with 25 in the equation.

So, y = 63.3 + .51 * 25

First, calculate .51 * 25 = 12.75

Then, add this to 63.3 to get y = 63.3 + 12.75 = 76.05

So, the estimate of y when x = 25 is 76.05.

Solution 2

To estimate y when x = 25 using the regression model y = 63.3 + .51x, you simply substitute x with 25 in the equation.

So, y = 63.3 + .51(25)

First, calculate the product of .51 and 25, which is 12.75.

Then, add this result to 63.3.

So, y = 63.3 + 12.75 = 76.05

Therefore, the estimate of y when x = 25 is 76.05.
