When the members of the senate are selected, only two members are minority students. The Minority Caucus claims that this Senate is racially biased. They decide to use statistics to prove their claim. Let X be the number of minority students who are selected for the senate. Assume that X~Binomial(n, p), then answer the following questions. The value of n is DECIMAL places) and the value of p is ? (round your answer to TWO QUESTION 8 Using Question 7, answer the following question. Assuming that the sentate represents the entire student body, how many minority students would you expect to be selected for the sentate? Use the formula: µ = n*p to find the expected value:
