For inference of a MEAN, the following are used to validate "approximately normal" EXCEPT: A. If the sample is less than 30, then the sample itself has no strong skew or any outliers

B. If the population is normal, then a sample of any size is also normal

C. Large Count condition of successes and failures are at least 10

D. The Central Limit Theorem with "n" at least 30

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?
