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.)

In a certain section of Southern California, the distribution of monthly rent for a one-bedroom apartment has a mean of $2,300 and a standard deviation of $220. The distribution of the monthly rent does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 70 one-bedroom apartments and finding the mean to be at least $2,250 per month? (Round z value to 2 decimal places and final answer to 4 decimal places.) Probability

The mean rent for a one-bedroom apartment in Southern California is $\$ 2,200$ per month. The distribution of the monthly costs does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 50 one-bedroom apartments and finding the mean to be at least $\$ 1,950$ per month? The standard deviation of the sample is $\$ 250 .$
