1. When we test for the statistical significance of the overall regression model, what are the null and alternative hypotheses being tested?
2. When we test for the statistical significance of an individual b coefficient, what are the null and alternative hypotheses being tested?
Homework Answers
We know that,
1. For overall regression model,
The hypothesis are,
- H0: β1 = β2 = ... = βp-1 = 0
H1: βj ≠ 0, for at least one value of j
2. For individual b coefficient,
The hypothesis are,
Ho: b = 0
Ha: b ≠ 0
The null hypothesis states that the slope is equal to zero, and the alternative hypothesis states that the slope is not equal to zero.
Thank you.

. When we carry out a statistical test with significance level α = 5%, the probability of rejecting the null hypothesis when it is true is 5%. Suppose that we independently select 5 random samples of size 100, and for each sample carry out the same statistical test with significance level 5%. We know that the null hypothesis is true. What is the probability that we reject the null hypothesis at most once out of the 5 tests? (a) 0.02...
