p=0.11

Then, a sample of n=160 is taken and the proportion of the sample is 0.10.

\hat{p}=0.10

The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.
