what is the null and alternative hypothesis for these two health questions?
Health question 1 Determining the effects of position change on the acute complications of coronary angiography
Health questions 2 compare patient outcome of vascular complications, back pain, and urinary discomfort between patients ambulatory 12-24 hours post-transfemoral cardia catheterization
Health questions 1
The null hypothesis H0: coronary angiography does not effects the position change on the acute complications (i.e. µ=µ0)
The alternative hypothesis H1: coronary angiography effects the position change due to the acute complications (i.e. µ≠µ0)
Health questions 2
The null hypothesis H0: There is no effect on health due to post-transfemoral cardia catheterization (i.e. µx=µy)
The alternative hypothesis H1:There is some effects on health due to post-transfemoral cardia catheterization (µx≠µy)
Where µx & µy are the mean effects due to treatment (before and after treatment)
