The Gallup Poll asked a random sample of 1785 adults whether they attended church during the past week.  Let p-hat be the proportion of people in the sample who attended church.  A newspaper report claims that 40% of all U.S. adults went to church last week.  Suppose this claim is true. 
Calculate the standard deviation of the sampling distribution.

The sampling distribution of a statistic is...

• Using repeated samples and finding a probabilitity

• The distribution of values taken by a statistic in all possible samples of the same sample size from the same population

• The way that sample results differe from each other

• the distribution of values in a sample of size n
