Suppose you invest $11,830.00 into an account earning an interest rate of 2.808% compounded continuously for 1 year(s) and thereafter earning an interest rate of 3.702% compounded monthly. How much money is in the account after 9 years?

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?
