C. none of these.

D. if the alternative hypothesis is true

In a one-sample hypothesis test, depending on how the alternative hypothesis is worded, we can have a:

A. one-tailed positive test.

B. one-tailed negative test.

C. two-tailed test.

D. all of these

In an analysis of variance experiment, if you obtain a significant interaction you:

A. look for Type I error

B. continue to test the other factors

C. none of these

D. stop

Answer 1

A p value of a statistic is the probability of obtaining that value or something greater or lesser if:

A. the null hypothesis is true. ( correct answer)

In a one-sample hypothesis test, depending on how the alternative hypothesis is worded, we can have a:

A. one-tailed positive test.

B. one-tailed negative test.

C. two-tailed test.

all of these. so option D is correct..

3) In an analysis of variance experiment, if you obtain a significant interaction you stop the test.
