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.
A 2-column table with 5 rows. Column 1 is labeled score with entries 1, 2, 3, 4, 5. Column 2 is labeled probability 0.18, 0.20 0.26, 0.21, 0.15.
Which of the following is the correct interpretation of P(X > 4)?
The probability of a randomly selected test having a score of at most 4 is 0.36.
The probability of a randomly selected test having a score of at least 4 is 0.36.
The probability of a randomly selected test having a score lower than 4 is 0.85.
The probability of a randomly selected test having a score higher than 4 is 0.15.
