Suppose there is a city where the mean cost per month of a one-bedroom apartment is $1,500, with a standard deviation of $250. Approximately what percentage of one-bedroom apartments in the city cost between $750 and $1,000?

The average cost of a one-bedroom apartment in a town is $650 per month. What is the probability of randomly selecting a sample of 50 one-bedroom apartments in this town and getting a sample mean of less than $630 if the population standard deviation is $100? (Round the values of z to 2 decimal places. Round your answer to 4 decimal places.)

Suppose two bedroom home prices followed a normal distribution with a mean of $398,000 and a standard deviation of $6,789. What percent homes cost $400,000 or less? what percent homes cost more than $400,000? Express your answer as a percent to one decimal place. Exclude the percent sign (%) in your answer.
