Use the Central Limit Theorem to find a mean given a probability Question The average home price in Massachusetts is $410,000, with a standard deviation of $65,000. A city planner is studying the distribution across the state of home prices in the bottom 10%. What price will indicate that a home is in the bottom 10% if the city planner examines 200 homes around the state? Use the z-table below: z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08...
