Consider the distribution of average number of hours that college students spend sleeping each weeknight. This distribution is very skewed to the right, with a mean of 5 and a standard deviation of 1. A researcher plans to take a simple random sample of 18 college students. If we were to imagine that we could take all possible random samples of size 18 from the population of college students, the sampling distribution of average number of hours spent sleeping will have a shape that is:
a. Less skewed than the population
b. Exactly normal
c. Just like the population (i. e., very skewed to the right)
d. It's impossible to predict the shape of the sampling distribution
