Run a regression analysis on the following bivariate set of data with y as the response variable.
| x | y |
|---|---|
| 62.4 | 39.2 |
| 62.2 | 40.4 |
| 47.7 | 68.9 |
| 120.5 | -36.5 |
| 49 | 37.9 |
| 69.1 | -9.4 |
| 53.2 | 71.8 |
| 66 | 13.8 |
| 87 | 8.4 |
| 92.3 | -1.6 |
| 70.3 | 17.8 |
Verify that the correlation is significant at an α=0.05α=0.05.
If the correlation is indeed significant, predict what value (on
average) for the explanatory variable will give you a value of 67.7
on the response variable.
What is the predicted explanatory value?

You run a regression analysis on a bivariate set of data (n=99).
You obtain the regression equation
y=0.843x+6.762
with a correlation coefficient of r=0.954 which is significant
at α=0.01 You want to predict what value (on average) for the
explanatory variable will give you a value of 150 on the response
variable.
What is the predicted explanatory value?
