Question

The captain of the Black Pearl has been providing his crew with a supply of citrus fruits. He is interested in determining if it is “unusually low” for 2 of the crew to come down with scurvy. The captain determines that the probability of only 2 of his crew coming down with scurvy to be 0.07. Given that our textbook states that an “event is unlikely if its probability is very small, such as 0.05 or less” (Triola, p. 141), determine whether the captain should conclude that the results are unusually low?

a) It would be unusually low because the probability of 0.07 cases is less than average.
b) It would not be unusually low because the probability of 0.07 is greater than the 0.05 requirement.
c) It would be unusually low because scurvy is contagious and the rest of the crew will get sick within 24 hours.

d) It would be unusually low because the probability of 0.07 is very small.

Explanation / Answer

option B is correct.

It would not be unusually low because the probability of 0.07 is greater than the 0.05 requirement.
