Is the average price of a new home in Dr. Kuter's hometown of South Bend different than the average price in Harare? The hypotheses in the image below are established to answer this question, where mu_1 denotes the mean price for new homes in South Bend and mu_2 is for Harare.To test the hypotheses, a random sample of 15 new homes in South Bend and a random sample of 15 new homes in Harare are obtained. Select the appropriate rejection region for this hypothesis test using a significance level of 0.05.

13. If a random sample of 20 homes in area A has a mean selling price of $128,000 and a standarddeviation of $4500, and a random sample of 20 homes in area B has a mean selling price of$125,000 and a standard deviation of $2500 can you conclude that there is a significantdifference between the variability in the selling price of homes in these two areas at the 0.05level?a) Solve using the P-value approach.b) Solve using the critical value approach

The average price of homes sold in the U.S. in 2012 was $240,000.  A sample of 144 homes sold in Chattanooga in 2012 showed an average price of $246,000.  It is known that the standard deviation of the population () is $36,000.  We are interested in determining whether or not the average price of homes sold in Chattanooga is significantly more than the national average.Compute the test statistic.

A report announced that the median sales price of new houses sold one year was $231,000,and the mean sales price was $271,600.Assume that the standard deviation of the prices is $90,000. Complete parts(a)through(d)below. ·○ (a) If you select samples of n=2,describe the shape of the sampling distribution of X. Choose the correct answer below. OA.The sampling distribution will be approximately uniform. O B.The sampling distribution is skewed to the right,but less skewed to the right than the population. OC.The sampling distribution will be approximately normal. OD.The sampling distribution will depend on the specific sample and will not have a constant shape.

You are trying to gauge how much you might need to spend to buy a house in a new locality. The data for the prices of the houses sold last year is available. The data shows some really expensive houses were sold in the locality and the price of no two houses seem to match in the sales data. What measures of central tendency are appropriate for the situation?
