- 5- Can you please make sure it's the right answers because I'm getting wrong answersJan's All You Can Eat Restaurant charges $9.10 per customer to eat at the restaurant. Restaurant management finds that its expense per customer, based on how much the customer eats and the expense of labor, has a distribution that is skewed to the right with a mean of $8.50 and a standard deviation of $3. Complete parts (a) and (b). a. If the 100 customers on a particular day have the characteristics of a random sample from their customer base, find the mean and standard deviation of the sampling distribution of the restaurant's sample mean expense per customer. The mean is 8.50. (Round to the nearest hundredth as needed.) The standard deviation is (Round to the nearest hundredth as needed.)The average American gets a haircut every 43 days. Is the average different for college students? The data below shows the results of a survey of 11 college students asking them how many days elapse between haircuts.
