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?

A recent study reported that 25% of the residents of a particular community lived in poverty. Suppose a random sample of 300 residents of this community is taken. We wish to determine the probability that 29% or mon in poverty. Complete parts (a) and (b) below. a. Before doing any calculations, determine whether this probability is greater than 50% or less than 50%. Why? O A. The answer should be less than 50%, because the resulting Z-score will be negative...
