Please list the steps- State hypothesis Critical values Test statistics decision and summarize A real estate agent compares the selling prices of randomly selected homes in two municipalities in southwestern Pennsylvania to see if there is a difference. The results of the study are shown below. Is there enough evidence to suggest that the average cost of a home in both locations is the same? Use ? = 0.01. Scott Sample size 35 Mean selling price $93,430 Population standard deviation $5602. Ligonier Sample size 40 Mean selling price $98,043 Population standard deviation $4,731

Question 15 (0.75 points) Recall the previous question where the real estate firm wants to see if the mean price of homes in 2010 have differed from the mean price in 2008. Based on your P-value, what is the conclusion if we test at the 0.05 level of significance? There is evidence to conclude that the mean price of homes in 2010 differ from the mean price in 2008. There is evidence to conclude that the mean price of homes...

A real estate agent has claimed that the average home prices in Lindville (L) and Jamesville (J) are equal. Suppose that a random sample of 18 Lindville homes resulted in a sample mean price of $235,000 with a sample standard deviation of $22,000. A random sample of 12 Jamesville homes resulted in a sample mean price of $245,000 with a sample standard deviation of $24,000. Test the real estate agent's claim at the 5% significance level. Assume that population variances...

In real estate, it is common knowledge that where the house is located is extremely important (many people summarize this by saying the three most important factors in home sales are location, location, and location). Many characteristics of a house are tied to its location, one of which is age. Some neighborhoods are considered "old" while others are considered "new," with new homes generally selling at a higher price. One way to compare "old" and "new" neighborhoods is to examine...
