Researchers conducted a study to determine the monthly rental cost of rent-controlled apartments in the five boroughs of New York City in 2012. The study randomly sampled 157 apartment records from the Bronx, obtained from a large collection of income- and expense-filing statements. The 95% confidence interval of rent-controlled apartment costs in the Bronx was $917.00 ± $22.10. The cost of all rent-controlled apartments in the Bronx has a standard deviation of $73.70. State the conclusion of the z-confidence interval for the mean. Researchers are certain that the interval ($894.90, $939.10) contains the mean.
