24.    House sales. The realty company in Exercise 21b looks at a recent sample of houses that have sold. On testing the null hypothesis that 50% of the houses take more than three months to sell against the hypothesis that more than 50% of the houses take more than three months to sell, they find a P-value of 0.034. Which of these conclusions is appropriate?

a)    There’s a 3.4% chance that 50% of the houses take more than three months to sell.

b)    If 50% of the houses take more than three months to sell, there’s a 3.4% chance that a random sample would produce a sample proportion as high as the one they obtained.

c)    There’s a 3.4% chance that the null hypothesis is cor- rect.

d)    There’s a 96.6% chance that 50% of the houses take more than three months to sell.
