On a coordinate plane, an absolute value graph has a vertex at (negative 1.5, negative 3.5). The graph shows the function f(x) = |x – h| + k. What is the value of h? h = –3.5 h = –1.5 h = 1.5 h = 3.5

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?
