A recent survey of 1500 residents in a city indicated that around 40% of the residents owned a home. Suppose that it is indeed true that 40% of the residents own a home. The sampling distribution for the proportion of home ownership is approximately normal with mean 0.40 and standard deviation 0.025. What is the probability the sample proportion of people who own a home will be less than 0.37?
