The cumulative frequency curve above shows the distribution of the scores of 50 students in an examination. Find the 36th percentile scores?
18%
28%
36%
50%
Correct answer is B
the 36th percentile i.e. 36% of the total frequency of 50.
\(\frac{36}{100}\) \(\times\) 50 = 18
= From the graph, 18 on the vertical axis corresponds to28 on the horizontal axis.
\(\therefore\) P\(_{36}\) = 28%
