Suppose you deposit your graduation cash gifts into an account that pays 4% annual interest compounded continuously. if you are 18 when you graduate, get $1000 in cash gifts and leave the money in the account until you are 30, how much money will you have? round to the nearest dollar.

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?
