Question

Using the information from the given histogram which of the following is one of the points used to construct the corresponding ogive?

• A. (28,76)
• B. (32,81)
• C. (16,20)
• D. (9,12)

Answer 1

The correct option is B

(32,81)

From the histogram the following frequency table can be constructed.

$\begin{array}{ccc}\text{Class Interval}& \text{Frequency}& \text{Cumulative Frequency}\\ 8-12& 9& 9\\ 12-16& 16& 25\\ 16-20& 22& 47\\ 20-24& 18& 65\\ 24-28& 12& 77\\ 28-32& 4& 81\end{array}$

Now by poltting the points (12,9), (16,25),(20,47),(24,65),(28,77),(32,81) we get the corresponding ogive.

Therefore option (b) is correct.
