Question

A random variable X is not normally distributed. It has a mean of 32 and a standard deviation of 4. List the givens with correct symbols: $\mu = 32$ $\sigma = 4$ a) If you take a sample of size 16, can you say what the shape of the sampling distribution for the sample mean is? ? Why or why not? Check all that apply. $\sigma$ is known n is less than 30 n is at least 30 $\sigma$ is unknown population is not normal population is normal b) For a sample of size 16, state the mean and the standard deviation of the sampling distribution of the sample mean. mean of the sampling distribution of the sample mean when n = 16: standard deviation of the sampling distribution of the sample mean when n = 16 rounded to two decimal places: c) If you take a sample of size 37, can you say what the shape of the distribution of the sample mean is? ? Why or why not? $\sigma$ is unknown n is less than 30 population is normal $\sigma$ is known population is not normal n is at least 30 d) For a sample of size 37, state the mean and the standard deviation of the sampling distribution of the sample mean. mean of the sampling distribution of the sample mean when n = 37: standard deviation of the sampling distribution of the sample mean when n = 37 rounded to two decimal places:
