Standardized tests for certain subjects, given to high school students, are scored on a scale of 1 to 5. Let X represent the score on a randomly selected exam. The distribution of scores for one subject's standardized test
is given in the table.
Score/Probability
1 - 0.18
2 - 0.20
3 - 0.26
4 - 0.21
5 - 0.15
Which of the following is the correct interpretation of
P(X > 4)?
1) The probability of a randomly selected test having a
score of at most 4 is 0.36.
2) The probability of a randomly selected test having a score of at least 4 is 0.36.
3) The probability of a randomly selected test having a score lower than 4 is 0.85.
4) The probability of a randomly selected test having a
score higher than 4 is 0.15.
