Suppose that the test score of a student taking the final of a probability course is a random variable with mean 68.3. (a) Give an upper bound for the probability (in three decimal places) that the student's test score will exceed 95. Answer: € Suppose that we know, in addition, that the standard deviation of the student's test score on the final is 4.3. (b) What is a lower bound of the probability (in three decimal places) that the student will score between 58.3 and 78.3 ?
