The average rent of a one-bedroom apartment in a town is $820 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 $790 if the population standard deviation is $100?

Step 1
First, we need to find the z-score for the sample mean of $790. The z-score is calculated as: z = (X - μ) / (σ / √n) where X is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size. Show more…

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.)
The average rent of a two bedroom apartment is $780 per month with a standard deviation of $110. If a random sample of 50 two bedroom apartments is taken, find the probability that a) the mean of the sample exceeds $820 per month. b) the mean of the sample is less than $750 per month.
