Homework Answers
It means that the 2 variables jointly hasto be tested using F test
The 2 variables individually can be tested using T test
A F test tells us that the variables are jointly different from zero but it does not mean that the all the estimated coefficients are different from zero individually, for that you use the T test to check if the coefficient variables are individually different from zero
Hence if we fail to reject the null hypothess for indivdual variables we should apply T test
but if we reject the null hypothesis for 2 joint variables we need to apply F test

11. If we reject the null hypothesis, what can we conclude, subject to the probability, α? Multiple Choice Reject the null with a probability, α, of making a Type I error. The alternative hypothesis is false. The null hypothesis is true. Both the null hypothesis and the alternative hypothesis are true. 12.

3. The following statements are very important. Give them some careful thought and discuss them (a) When we fail to reject the null hypothesis, we do not claim that it is abso- lutely true. We simply claim that at the given level of significance, the data were not sufficient to reject the null hypothesis (b) When we accept the alternate hypothesis, we do not claim that the null hypothesis is absolutely false. We do...
