(a) Describe the sampling distribution of
hat(p)
. Cheose the phrase thet best describos the shape of the sampling distribution. A. Approximately normal because
n<=0.05N
and
np(1-p)>=10
B. Not normal because
n<=0.05N
and
np(1-p)<10
C. Not normal because
n<=0.05N
and np(
1-p
D. Approximatoly nomal because n 50.05 N and ~
p
Determine the mean of the sampling distribution of
hat(p)
. 官
◻
(Round to two docimal places as needed.) Determine the standard deviation of the sampling distribution of
hat(p)
. a.
◻
(Round to six decimal places an needed) (b) What is the probability of obtaining
x=420
or more individuals with the chanaclerstic?
P(hat(p)>=0.42)=

x=350
or fower indviduals with the characteristic?
P(hat(p)<=0.35)=
