Rich is attending a 4-year college. as a freshman, he was approved for a 10-year, federal unsubsidized student
loan in the amount of $7,900 at 4.29%. he knows he has the option of beginning repayment of the loan in 4.5
years. he also knows that during this non-payment time, interest will accrue at 4.29%

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
