lem 15. A variable of a population has a mean of μ = 150 and a standard deviation of o = 21. sampling distribution of the sample mean for samples of size 49 is approximately normally distributed with mean ard deviation part (a) to be true, what assumption did you make about the distribution of the variable under consideration? Normal distribution. No assumption was made. Uniform distribution. e statement in part (a) still true if the sample size is 16 instead of 49? Why or why not? Yes, the sampling distribution of the sample mean is always normal. and No, the sampling distribution of the sample mean is never normal for sample size less than 30. No. Because the distribution of the variable under consideration is not specified, a sample size of at least 30 is needed for part (a) to be true.
