(a) Find the mean of p, where p is the proportion of minority member applications in a random sample of 1650 that is drawn from all applications. b) Find the standard deviation of p c) Compute an approximation for P(p≤1), which is the probability that there will be 10%or fewer minority member applications in a random sample of 1650 drawn from all applications. Round your answer to four decimal places.
A minority representation group accuses a major bank of racial discrimination in its recent hires for financial analysts. Exactly 12%of all applications were from minority members, and exactly 10% of the 1650 open positions were filled by members of the minority.
Answer the following.
(a) Find the
b) Find the standard deviation of p
c) Compute an approximation for P(p≤1), which is the
(a)
The mean of p is,
Thus, the mean of p is 0.12.
The mean number of minority member applications is .
b)
The standard deviation of p is,
Thus, the standard deviation of p is 0.008.
The number of applications is .
