Step 1 Exercise 29 gives a probability model for the grade of a randomly chosen student in Statistics 101 at North Carolina State University, using the 4-point scale. From Exercise 29: North Carolina State University posts the grade distributions for its courses online. Students in Statistics 101 in a recent semester earned 21% A's, 43% B's, 30% C's, 5% D's, and 1% F's. Here is the probability model for the grade of a randomly chosen Statistics 101 student. 0 (F) 1 (D) 2 (C) 3 (B) 4 (A) Grade Probability 0.01 0.05 0.30 0.43 0.21 What is the mean grade in this course? (Fill in the blank below and give your answer to 2 decimal places.) The mean is u =
