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?
