How long does it take to sell a house on the market? One survey by the property portal Home.co.uk reported that in the United Kingdom, houses for sale are on the market an average of 109 days. Of course, the length of time varies by market. Suppose random samples of 13 houses in Canterbury and 11 houses in Coventry that are for sale are traced. The data shown here represent the number of days each house was on the market before being sold. Use the given data and a 1% level of significance to determine whether the population variances for the number of days until sale are different in Canterbury than in Coventry. Assume the numbers of days for which houses are on the market are normally distributed.
