The UW student-athletes on the women's teams compete in various NCAA-I sports. Each team may be regarded as a random sample of all the NCAA-I athletes in that sport. The 14 players listed on the roster for the 2004-05 Women’s Basketball team had an average height of 69.67 inches with a standard deviation of 3.47 inches. Give a 99% confidence interval for the average height of NCAA-I women’s basketball players in that year. Write a one or two sentence summary in non-statistical language to describe what you have found, not how you found it. Your audience is people who have never had a statistics class (think of middle of the road 8th graders, not the really bright ones).

Starting on September 1, 2000 - the day he starts college - and ending on September 1, 2004, Craig borrowed $6500 a year to pay for college expenses (i.e. that's 5 withdrawals total).
After graduation, he decided to go to graduate school in mathematics, and his loans were deferred (i.e. they accrued interest, but no payments were due). After finishing graduate school, he began repaying his loans. Beginning on July 1, 2007, he made monthly payments for 8 years. Each payment increased by 2.6% over the previous payment. If his loans had a fixed nominal rate of 6% convertible monthly for the entire life of the loans, what was the size of his first payment?
