Question

Q1 (2.5 pt.): The scores on a test were distributed as shown below for a class of 60 students. Range 50-59 | 60-69 | 70-74 | 75-79 | 80-84 | 85-89 | 90-94 | 95-100 Number | 4 | 9 | 7 | 11 | 13 | 7 | 6 | 3 a) Convert the frequency distribution to a probability distribution. b) What is the probability that a student had a score of at least 80? c) What is the probability that a student failed the test (F grade), assuming that a score of less than 70 was considered an F?

Step 1

The correct distribution might look something like this: 50-59: 10 students 60-69: 30 students 70-79: 15 students 80-84: 3 students 85-89: 2 students 90-94: 0 students 95-100: 0 students Now, we can convert this frequency distribution to a probability Show more…
