If the population proportion is 0.38, what is\(\style{font-family:Times New Roman;}{\sigma_\widehat p^2}\)if we calculate\(\style{font-family:Times New Roman;}{\widehat p}\) using 20 samples?
▸
0.0118
▸
0.1085
▸
0.0190

Because\(\style{font-family:Times New Roman;}n\)is small, we cannot calculate\(\style{font-family:Times New Roman;}{\sigma_\widehat p^2}\)accurately.
