TJ filled his water bottle with 16 ounces of water. The water is leaking, though, at a rate of 0 2 ounces per second. If the water bottle now has 11 2 ounces of water inside, how many seconds have passed?

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?
