population proportion with a specified characteristic is p=0.8. Complete parts (a) through (c) below.
A. Approximately normal Decause ns. and per-p) 1.
OB. Not normal because n ≤0.05N and np(1-p) < 10.
C. Not normal because n ≤0.05N and np(1-p) ≥ 10.
OD. Approximately normal because n ≤0.05N and np(1-p) < 10.
Determine the mean of the sampling distribution of p.
HA 8 (Round to one decimal place as needed.)
P
Determine the standard deviation of the sampling distribution of p.
6A = .028284 (Round to six decimal places as needed.)
