Question

The following box plot shows the number of books sold each day at a store for 80 days. How many days did the bookstore sell 2 to 12 books? A box plot is drawn with end points at 0 and 16. The box extends from 2 to 12 and a vertical line is drawn inside the box at 7 40 60 70 80

Answer 1

Answer:

40 days

Step-by-step explanation:

Looking at the box plot:

2 is first quartile( Q1 ) and 12 is third quartile (Q3)

The number of days that the books store sold 2 to 12 books, that would be equivalent to Q2

We should remember that:

Q2 = Median of a data set = 50%

Therefore, the number of days that the books store sold 2 to 12 books =

80 days × 50/100 = 400/100

= 40 days.
