To determine whether people are contributing more to their IRA’s in 2004 compared to 2001 a sample of 150 clients at a brokerage firm in 2004 shows that people deposited an average of $1500 to their IRA’s with a sample standard deviation of $400. In 2001 at the same brokerage, a sample of 200 clients revealed a sample average amount deposited into IRA’s was $1425 with a standard deviation of $520. Based on the 2 samples, test to see if the average amount deposited in 2004 is higher than the average amount in 2001. (test at the 1% level of significance). (15) What is the p-value?
