For questions 4 & 5 consider the following scenario: Wildlife experts found that a certain species of Komodo dragons have an average length of 6.5 meters with a standard deviation of 0.70 meters. One of the experts fears that pollution might be affecting the natural growth of the dragons.

4. Provided the lengths are normally distributed, the probability that a Komodo dragon has a length of at most 6.2 meters is closest to:

A) 99.1% (B) 66.6% C) 33.4% D) 0.9% E) None of the aforementioned
Explain your rationale for the answer you chose:

5. If the scientists collect a random sample of 30 Komodo dragons and measure their lengths, the probability that the sample mean length is 19.5 long is:

A) 99.1% B) 66.6% C) 33.4% D) 0.9% E) None of the aforementioned
Explain your rationale for the answer you chose:
