Benihana Japanese restaurant in Cupertino has determined that the mean number of minutes it takes for each customer to dine is 45 with a standard deviation of 11 minutes. The restaurant plans to choose a random sample of n = 15 customers and determine the sample mean. Which of the following statements is true in this case?

a. The sampling error will be larger than if they had sampled n = 64 customers.

b. The sampling distribution may actually be approximately normally distributed depending on what the population distribution is.

c. There is no way to determine what the mean of the sampling distribution is without knowing the specific shape of the population.

d. The sampling distribution will have the same distribution as the population, provided that the population is not normally distributed.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
