Could you find a regression equation that would be acceptable as a statistically significant and yet offer no acceptable interpretational value to management? Detail the variables associated with the regression equation and explain how it is statistically significant. **I have come to the conclusion that yes, it is possible. But i am having trouble finding a data set to relate this to in addition to detailing the variables associated with the regression equation. Thanks!

Rejecting the null hypothesis can tell a researcher that a finding is statistically significant (for example, say there is a significant difference between students in our class and students in general) -- but this doesn’t tell us how extreme the difference really is (just that there is one). What statistical metric tells us how extreme a result is? (Or, in other words, the extent to which two population distributions do not overlap)? A. Effect size / Cohen’s D B. The...

statistics obtained from a sample. Select the two possible
