What’s the difference between p-value associated with the estimate of β (slope) of a
line versus the p-value associated with the F-ratio statistic for the model – in a linear
regression?
Homework Answers
Solution: The difference between p-value associated with the estimate of β (slope) of a line versus the p-value associated with the F-ratio statistic for the model – in a linear regression is:
The p-value associated with the estimate of slope of a regression line is based on t-distribution.
The p-value associated with the F-ratio statistic for the model in a linear regression is based on F-distribution.

Suppose you construct a simple linear regression model. Using 5 observations the LSE of the slope is calculated as 0.3 with associated standard error .86. Now you wish to test H0:β=0 versus H1:β≠0 at the 0.05 significance level. Applying an appropriate test, you reject null fail to reject null either reject or fail to reject null have no conclusion
