Please no written by hand solution and no img 2. A medical research team conducted a study to test the effect of a cholesterol-reducing medication. At the end of the study, the researchers found that of the 450 randomly selected subjects who took the medication, 30 died of heart disease. Of the 450 randomly selected subjects who took a placebo, 55 died of heart disease. Can you support the claim that the death rate due to heart disease is lower for those who took the medication than for those who took the placebo? Let the medication be population 1 and placebo be population . state the null hypothesis and alternative hypothesis Find the test statistic If the type -1 error a=0.05, find the critical values(s) and shade the rejection regions Base on the type 1-error a and rejection region(s), given above what is your conclusion (do noy use p-value to draw your conclusion)
