The sales of a certain product after an initial release can be found by the equation s=16square root7t+62, where s represents the total number of units sold and t represents the time in weeks after release. How many weeks will pass before the product sells about 150 units? Round your answer to the nearest week.

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?
