Answer 2

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the box plot shows the number of books sold each day at a store for 80 days.

A box plot is drawn with end points at 0 and 16.  It means minimum value is 0 and maximum is 16.

The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.

He have to find the number of days in which the bookstore sell 2 to 12 books.

2 is first quartile and 12 is third quartile, we know that

$Q_1=25\%$

$Q_3=75\%$

$Q_3-Q_1=75\%-25\%=50\%$

The data lies between Q₁ and Q₃ is 50% of the data.

$80\times \frac{50}{100}=40$

The bookstore sell 2 to 12 books in 40 days.

Therefore, the correct option is 1.
