The t-test for the hypothesis of a zero slope requires normality while the F-test for a zero slope does not?
A.The statement is false because t-test for zero slope and F-test agree numerically.
B.The statement is false because t-test for zero slope and F-test are functionally related
C.The statement is true

Suppose you conducted a simple linear regression t-test with a null hypothesis that the slope was positive. You obtained a p-value of 0.023. If you were to conduct an F-test that tested for a linear relationship between the one predictor and response what p-value would you expect to obtain?

True or False? when sample data occurs in pairs, an advantage of choosing a paired t-test is that it tends to increase the power of a test, as compared to treating each sample independently. True or False? When testing the difference between two population proportions, it is necessary to use two samples with the same sample size. True or False? If the sample proportions are p1=6/90 and p2=4/100, we can assume normality for the two sample proportions in a test...
