Question

You are interested in determining whether an experimental birth control pull has the side effects of changing blood pressure. You plan to randomly sample 18 women from the city in which you live. You give half of them a placebo for a month and then measure their diastolic blood pressure. Then you switch them to the birth control pill for a month and again measure their blood pressure. The other 9 women receive the same treatment except they are given the birth control pill first for a month, followed by the placebo for a month. What is the power of your study to reject the null assuming that the alternative. Assume alpha =.05 non directional alternative hypothesis.

State the null hypothesis below.

State the alternative hypothesis below.

What set of results obtained would allow you to reject the null hypothesis.

What is the power to detect a false null hypothesis assuming Preal=.9. Put your work and answer below.

What is the probability of failing to reject the null if the null is false assuming Preal =.9. Put your work and answer below.

What is the power to detect a false null hypothesis assuming Preal=.7. Put your work and answer below.

What is the probability of making a type 2 error assuming Preal =.7. Put your work and answer below.

****YOU APPRENTLY DO NOT NEED ANY DATA IT ONLY LOOKS FOR POWER***

Explanation / Answer

THe null and alternative hypothesis is

H0: an experimental birth control pull does not has the side effects of changing blood pressure

H1: an experimental birth control pull has the side effects of changing blood pressure

Assume alpha =.05 non directional alternative hypothesis.

When the t-test is p-value is less than 0.05 level of significance, reject the null hypothesis.
