A random variable is normally distributed. It has a mean of 249 and a standard deviation of 22. 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 you take a sample of size 40, can you say what the shape of the distribution of the sample mean is? Why? If the sample size is 40, 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 sample size is greater than 30. If the sample size is 40, then you can say the sampling distribution of the sample mean is not normally distributed since the sample size is greater than 30. If the sample size is 40, then you can say the sampling distribution of the sample mean is normally distributed since the variable is normally distributed. For a sample of size 40, state the mean of the sample mean and the standard deviation of the sample mean. Round to two decimal places if…
