A minority representation group accuses a major bank of racial discrimination in its recent hires for financial analysts. Exactly 10% of all applications were from minority members, and exactly 8% of the 900 open positions were filled by members of the minority. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of minority member applications in a random sample of 900 that is drawn from all applications. (b) Find the standard deviation of p. (c) Compute an approximation for P ps0.08), which is the probability that there will be 8% or fewer minority member applications in a random samnle of 000 from all anplis
