A restaurant is deciding which farm to order berries from for a seasonal dessert on their menu. The average cost for a pound of berries in California is $2.12 with a population standard deviation of $0.35. Assume that berry cost in California is normally distributed. Suppose that farms in California sell 10 different kinds of berries.
A. Explain why the sampling distribution of sample means is approximately normal.
B. Compute the mean, fa, and standard error, o= (rounded to three decimal places), for the sampling distribution of sample means (show the calculation to earn full credit).
C. The restaurant found a farm in LA that sells their berries for an average cost of $1.75, Is this farms average berry cost unusual? Explain why or why not (show the calculation with answer rounded to two decimal places to earn full credit).
