so likeee I don't know what this means but the frapg is showing range and that needs to be solved. The possible answer are: [-4,8] | (-4,3)U(3,8] | (-4,8] | [-4,3)U(3,8)

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?
