A random sample of n=263 measurements is drawn from a
binomial population with probability of
success 0.79. Complete parts a through c below.
a. Find ​E(p​) and σp. The mean of the
sampling distribution of p is enter your response
here. The standard deviation of the sampling distribution
of p is enter your response here.
​(Round to four decimal places as​ needed.)
Part 2
b. Describe the shape of the sampling distribution
of p.
A.The shape of the sampling distribution of p is
approximately normal because the sample size is large.
B.The shape of the sampling distribution of p is
approximately normal because the sample size is small.
C.The shape of the sampling distribution of p is
approximately uniform because the sample size is small.
D.The shape of the sampling distribution of p is
approximately uniform because the sample size is large.
Part 3
c. Find Pp<0.8. The probability that p is
less than 0.8 is enter your response here.
