Question 1162407: A national caterer determined that 37% of the people who sampled their food said that it was delicious. A random sample of 144 people is obtained from a population of 5000. The 144 people are asked to sample the caterer's food. If P-hat is the sample proportion saying that the food is delicious, what is the standard deviation of the sampling distribution of the sample proportion, p-hat?

The standard error is sqrt (p*(1-p)/n)
=sqrt (0.37*0.63/144)
=0.0402
