Answer 1

Answer #1

Please don't hesitate to give a "thumbs up" for the answer in case the answer has helped you

Standard error , s = sqrt(MSE)

But MSE = SSE/(n-m), where m = 1 ( number of predictors), and n = sample size = 8

MSE= 1225/7 = 175

So, s = sqrt(175) = 13.229

Hence, answer is : Standard error = 13.229
