Question:
The following graph is from Google Maps shows the distributionof typical customers at Chick-fil-A. Assume this is typicalof every day. Assume this would be the distribution of thepopulations of all customers at Chick-fil-A. The graph goesfrom about 7 am to 9 pm. The distribution looks bimodal witha mean of about 30 customers with a standard deviation of 15customers.
Assume a sample of the mean number of customers is taken atrandom times during the day. Assume the sample was 18randomly selected times.
Would the sampling distribution of mean customers be normallydistributed?
Why or why not?
Group of answer choices
No, because the sample size is 30 and that is large enough forthe Central Limit Theorem to be applied.
Yes, because although the population is bimodal, the CentralLimit Theorem states that the sampling distribution will benormal.
No, because the population is bimodally distributedand n<30, so the Central Limit Theorem does not apply.
Yes, because the sample size is 18 and that is large enough forthe Central Limit Theorem to be applied.
