For Problems 1 - 5, perform each hypothesis test. Assume that all random samples had an equal chance of being chosen. For each problem, complete the following steps:(a) State the null and alternative hypothesis.(b) Determine which distribution to use for the test statistic, and state the level of significance. (c) Calculate the test statistic.(d) Draw a conclusion and interpret the decision.   5. A student organization that promotes diversity believes that the percentage of minority students is no longer 35%. In a random sample of 250 students, 97 of the students are minorities. Does this evidence support the organization’s claim that the percentage of minority students is not 35% at the 0.01 level of significance? The registrar reports that 38% of currently enrolled students are minorities according to their admissions records. Based on this new information, did the organization draw the correct conclusion? If not, what type of error was made?
