B. Not normal because n s0.05N and np(1 - p)< 10.
C. Approximately normal because ns0.05N and np(1 - p) < 10.
D. Not normal because ns0.05N and np(1 - p) 2 10.
Determine the mean of the sampling distribution of p.
HA =
(Round to one decimal place as needed.)
Determine the standard deviation of the sampling distribution of p.
OA =
(Round to six decimal places as needed.)
(b) What is the probability of obtaining x= 32 or more individuals with the characteristic? That is, what is P(p20.64)?
P(20.64) =
