You are interested indetermining whether an experimental birth control pull has the sideeffects of changing blood pressure. You plan to randomly sample 18women from the city in which you live. You give half of them aplacebo for a month and then measure their diastolic bloodpressure. Then you switch them to the birth control pill for amonth and again measure their blood pressure. The other 9 womenreceive the same treatment except they are given the birth controlpill first for a month, followed by the placebo for a month. Theblood pressure readings are shown here. What is the power of yourstudy to reject the null assuming that the alternative hypothesisis true. Assume alpha =.05 non directional alternative hypothesis.YOU DO NOT NEED ANY DATA IT ONLY LOOKS FOR POWER
