I can't figure out what the standard deviation would be. What is the formula used to arrive at the conclusion?

Suppose we have a binomial experiment in which success is defined to be a particular quality. or attribute that interests us. Suppose n =34 and p= 0.25

n-p =8.5

n-q =25.5

a). What are the values of mu (mean) and Q (Sigma) (For each answer, enter a number. Use 3 decimal places.)

mp = 0.25

Qp = ?

b). Suppose n =56 and p = 0.36 (For each answer, enter a number. Use 2 decimal places)

n-p = 20.16

n-q = 35.84

What are the values of Mp and Qp? (For each answer, enter a number. Use 3 Decimal places)

Mp = 0.36

Qp = ?
