> Which of the following applies to Central Limit Theorem?Ans: Distribution of sample means may be assumednormal as long as sample size is greater than orequal to 30.> In order to apply the Central Limit Theorem?Ans: A sample size greater than or equal to 30> A random sample of size is 50 is selected froma known population with a mean of 13 and a standarddeviation of 3.3. Samples of the same size are repeatedly collected, allowing a sampling distribution of sample means to be drawn. What is the approximate standard deviation of the sample means?Ans: 0.467> A random sample of size 50 is selected from a known population with a mean of 25 and a standard deviation of 5.2. Samples of the same size are repeatedly collected, allowing a sampling distribution of samplemeans to be drawn. What does the problem tells us?Ans: The sampling distribution of sample mean will be approximately a normal curve> If the population is normally distributed?
