Question

Ennifer's boss asked her to make a box plot of the number of people who go to White Plains throughout the week. Here are the numbers of people she counted each day: 150, 210, 200, 85, 450, 180, 250

Answer 1

The answer is below

Explanation:

We are asked to create a box plot. To create a box plot, we need to determine the minimum point, maximum point, lower quartile, upper quartile, interquartile range, median.

First we have to arrange the data in ascending order. This gives:

85, 150, 180, 200, 210, 250, 450

The minimum point = 85

The maximum = 450

`Median=(2)/(4)(n+1)^(th)term=(2)/(4)(7+1)=4^(th)\ term=200\\\\Median=200 \\\\Lower\ quartile(Q_1)=(1)/(4)(n+1)^(th)term=(1)/(4)(7+1)=2^(nd)\ term=150\\\\Lower\ quartile(Q_1)=200 \\\\Upper\ quartile(Q_3)=(3)/(4)(n+1)^(th)term=(3)/(4)(7+1)=6^(th)\ term=250\\\\Upper\ quartile(Q_3)=250 \\\\Interquartile\ range=Q_3-Q_1=250-150=100`
