The largest fall was in New York, where average rents fell nearly 20% to $44.69 per square foot annually (The Wall Street Journal, January 8, 2010). The following table lists the average rent per square foot for 10 cities during the fourth quarter of 2009.

a. Specify the competing hypotheses to determine whether the median rent is greater than $25 per square foot.
b. Calculate the value of the test statistic. Assume the normal approximation for T.
c. Calculate the p-value.
d. At the 1% significance level, can you conclude that the median rent exceeds $25 per square foot?
