Question: A Realtor wishes to assess whether a difference exists, at a significance level of 0.05, between home prices in three subdivisions. Independent samples of homes from each of the three subdivisions – 18 homes in total - are obtained and their prices are recorded. The analysis of variance results for comparing these prices is started below.

a) What are the null and alternative hypotheses that we need to test?

b) Complete the blanks in the table.

c) What is the value of the estimate of the common population standard deviation of the populations of home prices in the three subdivisions?

d) What is your estimate of the P-value for this F test?

e) What is our conclusion for the hypothesis test?
