Run a regression analysis on the following bivariate set of data with y as the response variable. x y 26.1 54.3 28.4 42.5 33.8 50.2 63.4 63.3 64.3 79.4 72.5 76.1 46.2 57.4 70.2 82.1 50.5 64.3 55.4 58.8 40.7 48.5 69.4 57.5 40.4 47.8 45.1 60 64 72.5 50.6 56.9 44.2 65.6 Verify that the correlation is significant at an α = 0.05 . If the correlation is indeed significant, predict what value (on average) for the explanatory variable will give you a value of 59.2 on the response variable. What is the predicted explanatory value? x = Incorrect (Report answer accurate to one decimal place.)

Solutions

Expert Solution

(1) From the given data

Test for Correlation Coefficient:

H0: There is no relation between X and Y

H1: There is relation between X and Y

Thus we conclude that there exist relation between X and Y

Regression equation:

Given X = 59.2

Y-hat = 29.779 + 0.614*59.2 = 66.1

The predicted explanatory value of Y is 66.1
