Question

MEDAL + FAN!

The box plots below show the lifespan, in months, of laptop batteries manufactured by four companies:

Answer 1

Based on the data, which company manufactures batteries having the greatest variation in lifespan?

a. Company A
b. Company B
c. Company C
d. Company D

Answer 2

I think the answer is either C or D, but I'm not sure which one it is :/

Answer 3

do I go by the length of the whole line or the box part?

Answer 4

It would be C

because the box median is farther away from the total median

Answer 5

:)

Answer 6

When you copy and paste the plots, it says the exact points:

Company C shows minimum at 20, first quartile at 21, median at 22, third quartile at 24, and maximum at 28.

Company D shows minimum at 19, first quartile at 20, median at 22.5, third quartile at 23.5, and maximum at 27.

Since Company D's median is higher than Company C's median, does that mean that Company D would actually be the correct answer? Sorry for asking a stupid question and thank you for the help! It's just been so long since I've done this stuff.

Answer 7

Sadly, it wasn't C :/ But for anyone who needs to know in the future, I think the correct answer is D!

Answer 8

I was gonna say that, but I figured Nasa was right. I'm so sorry.
