Compute the Standard Error of a Sampling Distribution

Compute the standard error of a sampling distribution.
-Grandma Gertrude's Chocolates, a family owned business, has an opportunity to
Supply its product for distribution through a large coffee house chain. However, the
Coffee house chain has certain specifications regarding cacao content as it wishes to
Advertise the health benefits (antioxidants) of the chocolate products it sells. Suppose
Quality control inspectors at the coffee house chain take a sample of 100 pieces of this
Chocolate product from an incoming shipment. They find a sample average of 60% cacao
With a sample standard deviation of 8%. What is the standard error of the sampling
Distribution of the sample mean?

A) 8%
B) 0.8%
C) 6%
D) 0.6%
E) 0.08%
