Westlake Community Center was looking for a new activities director. Advertising expenses
totaled $600 and interviewing expenses, including
travel for four of the candidates, totaled $2,400.
Hiring expenses included $3,578 in moving costs
and a 6.7 percent realtor's fee on the selling price
of the director's home. The home sold for
$156.785. What is the total recruiting cost?

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?
