Please Help Me With This Question I Need The Answer class=

Sagot :

Given the box plot showing the number of hours 220 people spent at a computer on a weekend

Where, 6 hours is the lower quartile of the box plot,

The formula for the lower quartile is

[tex]\text{Lower quartile}=\frac{N}{4}[/tex]

Where, N is the number of people, i.e N = 220

Substitute for N into the formula for the lower quartile

[tex]\text{Lower quartile}=\frac{N}{4}=\frac{220}{4}=55\text{ people}[/tex]

Since the lower quartile represents the number of people who spent less than 6 hours

The number of people who spent more than 6 hours will be

[tex]=220-55=165\text{ people}[/tex]

Hence, the answer is 165 (last option)
