Run a regression analysis on the following bivariate set of data with y as the response variable.
x | y |
---|---|
58.6 | 56.3 |
66.3 | 72.1 |
54.8 | 119.2 |
57.4 | 83.2 |
62.8 | 74.3 |
77.6 | 72.2 |
71.8 | 62.2 |
46.4 | 77.2 |
77.4 | 86.6 |
60.5 | 78.4 |
66.4 | 131.3 |
76.4 | 113.5 |
68.5 | 84.2 |
81.5 | 102 |
77.5 | 136.3 |
49 | 12.2 |
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 82.3 on the
response variable.
What is the predicted explanatory value?
x =
(Report answer accurate to one decimal place.)
Correlation is coming out to be not significant so we can't use the regression line to predict response variable from the explanatory variable.
