If all the possible random samples of size n = 5 are selected from a population of μ=50 and σ=5 and the mean is computed for each sample, then what shape is expected for the distribution of sample means?

a. There are thousands of possible samples and it is impossible to predict the shape of the distribution.

b. The sample means tend to form a normal distribution only if the population distribution is normal.

c. The sample means tend to be distributed evenly across the scale, forming a rectangle-shaped distribution.

d. The sample means tend to form a normal-shaped distribution whether the population is normal or not.
