okay guys so another question for user 8782 723 and also won't let me comment so if you see this question that's why I didn't comment back something's just wrong with my and also know I didn't copy it from a website I actually wrote it down because I had saw something about this before and I took a picture of it and it just did a lot of dots so that's why I did that ​

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?
