A AND B Question 8:Suppose we are interested in comparing the proportion of male students who smoke to theproportion of female students who smoke. We have a random sample of 150 students (60 malesand 90 females) that includes two variables: Smoke = "yes" or "no" and Gender = "female (F)" or"male (M)." The two-way table below summarizes the results.%3DSmoke = YesSmoke = NoSample Size60Gender = MGender = F519.8190a. If the parameter of interest is the difference in proportions, pm - pf, where pm and pfrepresent the proportion of smokers in each gender, find the difference in proportionsbased on the data in the table. Report your answer with two decimal places.b. Describe how to use the data to construct a bootstrap distribution. What value should berecorded for each of the bootstrap samples.

It is given that:- smoke=yes smoke=no…

Question 8: Suppose we are interested in comparing the proportion of male students who smoke to the proportion of female students who smoke. We have a random sample of 150 students (60 males and 90 females) that includes two variables: Smoke = "ves" or "no" and Gender = "female (F)" or "male (M)."
