Question 14 of 30The histogram below gives the distribution of test scores for a sample ofstudents in a school in Alaska. Which answer choice gives the number ofstudents that scored above 50.57

Answer 1

We need to find the number of students that scored above 50.57.

That number is given by the sum of all heights of the bars after 50.5:

Heights of the bars with scores above 50.5:

• bar labeled 1: ,100

• bar labeled 2: ,250

• bar labeled 3: ,200

• bar labeled 4: approximately ,190

• bar labeled 5: approximately ,60

Then, adding those values, we obtain:

$100+250+200+190+60=800$

Answer: D. 800
