QUESTION 5 24 points In a lame statistics course, an exam has 25 problems. Each problem has 5 answer choices, with one correct answer each, To score the exam, correct answers add 4 points each, and incorrect answers subtract 1 point each.

The expected value for the score on a student's exam is: -(Round answer to the nearest whole number) B. The standard error for the score on a student's exam is : (Round answer to the nearest whole number) C. The professor decides that a total score of 15 points or more is required to pass.
