You borrow $2250 at 4.8% compounded weekly for tuition. While you do not have to make payments for the 5 years that you are in school, the interest is compounding. What is your loan balance after the 5-year grace period (if you've made no payments)?

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?
