Answer to Problem 1RE

  H0:p1p2=0H1:p1p2>0

Explanation of Solution

It is given in the question that a report in the journal of medicine notes growing evidence that the herb can cause urinary tract cancer in those who take it. Suppose we are asked to design an experiment to study this claim. Then we have the subjects who have used this herb and those who do not have used this herb. Thus, the null hypothesis is that there is no difference in cancer rates and the alternative hypothesis is that the rate is higher for those using the herb. So, we define hypotheses as:

  H0:p1p2=0H1:p1p2>0
