13. For a sample of 42 rabbits, the mean weight is 5 pounds and the standard deviation of weights is 3 pounds. Which of the following is most likely true about the weights for the rabbits in this sample? 
选项为:A:The distribution of weights is approximately normal because the sample size is 42, and therefore the central limit theorem applies.  B:The distribution of weights is approximately normal because the standard deviation is less than the mean.  C:The distribution of weights is skewed to the right because the least possible weight is within 2 standard deviations of the mean.  D:The distribution of weights is skewed to the left because the least possible weight is within 2 standard deviations of the mean.  E:The distribution of weights has a median that is greater than the mean.  请回答其中一个选项.
