You would like to see if the standard deviation (variability) for the number of days a property is on the market before it sells in New York City (NYC) is greater than the standard deviation of the number of days a property is on the market before it sells in San Francisco (SF) for this current year.Use the information below and do a hypothesis test to see if the standard deviation of the number of days a property is on the market before it sells in New York City (NYC) is greater than the standard deviation of the number of days a property is on the market before it sells in San Francisco (SF) for this current year.Use a level of significance of .05.

A.What will be the alternative hypothesis?

B.What is the test statistics value (correct number of decimal places depending on which test statistic)?

C.What is the probability of the test statistic for this specific problem? (take into consideration if this is 1-tail or 2-tail test)

D.What conclusion will you come to? .Use a level of significance of .05.

E.Using the critical value approach at what critical value will you start rejecting the null hypothesis?
