A person deposits $2,000 each year for 25 years into an IRA. When she retires immediately after making the 25 th deposit, the IRA is worth $220,000 . (A) Find the interest rate earned by the IRA over the 25-year period leading up to retirement. (B) Assume that the IRA continues to earn the interest rate found in part (A). How long can the retiree withdraw $30,000 per year? How long can she withdraw $24,000 per year?

The accompanying table contains the data for the amounts (in oz) in cans of a certain soda. The cans are labeled to indicate that the contents are 20 oz of soda. Use the sign test and
0.05 significance level to test the claim that cans of this soda are filled so that the median amount is 20 oz. If the median is not 20 oz, are consumers being cheated?
