Suppose we take samples of size 53 from a population whose mean is 45 with a standard deviation of 4. Describe the shape of the means of the sampling distribution. Why? Approximately normal, np and n(1-p) are both greater than 10. Unknown, the shape of the sampling distribution cannot be determined since we do not know the shape of the population distribution. Not approximately normally distributed. The sample sizes are not large enough. Approximately normal, the Central Limit Theorem will apply here since the sample sizes are larger than 30
