The points scored by teams in the first round of the Statistics Games have a mean of 135 points and a standard deviation of 27 points. A random sample of 36 teams is taken. Can we use a normal model for the sampling distribution? Why or why not?   A) No, because the standard deviation is too large. B) No, because we're not calculating a mean. C) No, because the sample is not big enough. D) Yes, because we have a random sample, and the sample size is more than 30. E) Yes, because sample size is more than 20.
