Answer:
Researchers are<u> 95%</u> certain that the interval ($2005.76, $2024.24) contains the mean monthly rental cost of <u>all rent-controlled apartments in Brooklyn</u>.
Step-by-step explanation:
Last part of the question and choices are missing. Full question is like this:
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 203 apartment records from Brooklyn, obtained from a large collection of income- and expense-filing statements. The 95% confidence interval of rent-controlled apartment costs in Brooklyn was $1,025.00 ± ± $9.24. The cost of all rent-controlled apartments in Brooklyn has a standard deviation of $67.20. State the conclusion of the z z -confidence interval for the mean.
Researchers are ________certain that the interval ($2005.76, $2024.24) contains the mean monthly rental cost of _____.
all rent-controlled apartments in New York City.
all rent-controlled apartments in Brooklyn.
the 98 apartments in the sample.
all apartments in Brooklyn.
Confidence Intervals give a range of values that the statistic (mean cost of all rent-controlled apartments in Brooklyn) can assume in a <em>confidence level </em>(95%). Confidence levels give the levels we can be sure (95%) that the statistic falls within the interval.
Since the sample is about the rent-controlled apartments in Brooklyn, the confidence interval gives an estimate of the rent-controlled apartments in Brooklyn, not in New York.
