A random variable is not normally distributed, but it is mound shaped. It has a mean of 17 and a standard deviation of 5. If you take a sample of size 13, can you say what the shape of the sampling distribution for the sample mean is? Why? If the sample size is 13, then you can't say anything about the sampling distribution of the sample mean, since the population of the random variable is not normally distributed and the...
