A real estate agent compares the selling price of homes in two suburbs of Seattle. the results of the study are shown below. suburb
1: X1= $59,102, s1= $4731, n1= 40 suburb
2: X2= $63,255, s2= $5602, n2= 35 is there evidence to support the average cost of a home in suburb 1 is less than the average cost of a home in suburb 2? use ?=0.01. Assume the population standard deviations are equal.
Find the critical value and the test static as well.

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...

A real estate agent claims that the average price of a home sold in Beaver County, Pennsylvania, is $60,000. A random sample of 35 homes sold in the county is selected, and the prices in dollars are shown. Is there enough evidence to reject the agent's claim at 1 = 0.05? Assume @ = $76,025 and X = $84,581.43.

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...

4) A real estate agent believes that the average closing cost of purchasing a new home is $6500.00 over the purchase price. She selects 40 new homes sales at random and finds the average closing costs to be $6600.00. The population standard deviation is $120.00. Test this claim at alpha equal to 0.05. use the following three methods: Traditional Method P-value Confidence Interval a) Ho: H: b) alpha: cv: c) Test Value: d) Decision: e) Summarize results:

Consider independent random samples from two populations that are normal or approximately normal, or the case in which both sample sizes are at least 30. Then, if σ1 and σ2 are unknown but we have reason to believe that σ1 = σ2, we can pool the standard deviations. Using sample sizes n1 and n2, the sample test statistic x1 − x2 has a Student's t distribution where t = x1 − x2 s 1 n1 + 1 n2 with degrees...

A recent publication states that the average closing cost for purchasing a new home is $7654. A real estate agent believes the average closing cost is different than $7654. She selects 28 new home purchases and finds that the average closing costs are $8270 with a standard deviation of $183. Help her decide if she is correct by testing her claim at αα=0.01. The correct hypotheses would be: H0:μ≤$7654H0:μ≤$7654 HA:μ>$7654HA:μ>$7654 (claim) H0:μ≥$7654H0:μ≥$7654 HA:μ<$7654HA:μ<$7654 (claim) H0:μ=$7654H0:μ=$7654 HA:μ≠$7654HA:μ≠$7654 (claim) Since the level...
