20. In a class, grades fall into the following distribution: A: 25%; B: 35%; C: 20%; D: 15%, F: 5%. Assign these values to a random digit table and run (using line 135) for a sample of 10 students. Proposed Solution: Assignments (since the question is referring to grades): A: 90 to 00; B: 80 to 89; C: 70 to 79; D: 60 to 69; F: 01 to 59 Line 135: 71435 51648 89675 97778 becomes: 71 43 55 16 48 89 67 59 77 78 SO C F F F F B D DCC A: 0; B: 1; C: 2; D: 2; F: 4 What is wrong with the proposed solution? A. The tallying of letter grades was miscounted. B. The assignment of letter grades to digits was not based on the percentage distribution. C. Line 135 of the Random Digit Table was not used. D.
