A real estate agent claims that the mean living area of all single-family homes in his county is at most 2400 square feet. A random sample of 50 such homes selected from this county produced the mean living area of 2540 square feet and a standard deviation of 472 square feet. a. Using $\alpha=.05$, can you conclude that the real estate agent's claim is true? What will your conclusion be if $\alpha=.01 ?$

The U.S. Census Bureau reported that the mean area of U.S. homes built in 2012 was 2505 square feet. A simple random sample of 22 homes built in 2013 had a mean area of 2618 square feet with a standard deviation of 204 feet. Can you conclude that the mean area of homes built in 2013 is greater than the mean area of homes built in 2012? It has been confirmed that home sizes follow a normal distribution. Use a 10% significance level.Round to the fourth Ho: mean = please provide number __?__ Ha mean > please provide number __?__ Test Statistic: __?__P-value: __?__

It is hypothesized that the mean size of new homes in California is 2290 square feet. A random sample of 100 new homes in California yielded a sample mean of 2347. Assume the true standard deviation is known as 257 square feet. Perform the test H0: µ = 2290 vs. H1: µ > 2290 using the p-value approach to determine if the true mean square footage is greater than 2290. First compute the p-value, then draw your conclusion. The significance level is assumed to be 0.05.

Use the following information to answer the next ten questions. The data that follow are the square footage (in 1,000 feet squared) of 28 homes. $$\begin{array}{|c|c|c|c|c|c|c|}\hline 1.5 & {2.4} & {3.6} & {2.6} & {1.6} & {2.4} & {2.0} \\ \hline 3.5 & {2.5} & {1.8} & {2.4} & {2.5} & {3.5} & {4.0} \\ \hline 2.6 & {1.6} & {2.2} & {1.8} & {3.8} & {2.5} & {1.5} \\\hline {2.8}&{1.8} &{4.5}&{1.9} &{1.9}& {3.1}& {1.6}\\\hline\end{array}$$ $$\text{Table 5.4}$$ The sample mean $=2.50$ and the sample standard deviation $=0.8302.$ The distribution can be written as $X \sim U(1.5,4.5).$ In this distribution, outcomes are equally likely. What does this mean?
