Question

(10) Use the following freauency bar graph to answer the following questions.Chart of MTH 150 GradescountGradesa) How many students received a C for the course?b) How many students passed the course (with a C or higher)?c) How many students received no credit for the course (i.e. got an F)?d) How many total students took the course?e) Which letter grade represents the mode?

Answer 1

From the frequency bar graph, we can read the following information.

15 students got an A

6 students got a B

5 students got a C

10 students got a D

14 students got an F

a) As described above, 5 students got a C

b) Adding up the frequencies of the students who got C or higher:

5 + 6 + 15 = 26

26 students passed the course

c) Assuming the students who did not pass got any credits, then we add up the students with D and F: 10 + 14 = 24

24 students received no credit for the course

d) Total students in the course: 15 + 6 + 5 + 10 + 14 = 50

e) The mode is the letter grade that got the highest frequency:

Mode = A

A got 15
