2) You wish to know if the distribution of preferences for cake, ice cream, or cookies differs across men and women. The nullhypothesis is that these variables are independent; that is, the distribution is the same across men and women. You collect data from60 Americans and find the following:CakeIce Cream10-Men•Women101215Cookies85•Conduct a chi square test for independence and draw a conclusion.+3) Study and then define, give examples of, and write out notation for set, subset, union, intersection, sample space, event, andcomplement of an event.4) Consider a partition of the sample space representing possible states of reality (drug helps, null, drug hurts). You initially assumethat P(helps)=.45, P(null)=.10, P(hurts)=.45. You collect data and you find that P(data/helps)=.3, P(data null)= 2, andP(data/hurts).1. Apply Bayes Rule to compute your updated probability that the drug helps.

Since you have posted multiple questions, we will provide the solution only to the first question as…
