Question

19. The heights, in inches, of players on a basketball team are:

57, 63, 68, 72, 50, 63, 65, 69, 73, 71, 60
The heights, in inches, of players on a soccer team are:
49, 53, 52, 52, 57, 61, 55, 61, 59, 61, 50, 50, 51, 62, 50, 57

What is the difference in mean height between the basketball team and soccer team?

Answer 1

Hello!

Let's find the mean of each team. Let's add up all of the heights and divide by number of players.

57+63+68+72+50+63+65+69+73+71+60=711

711/11≈64.64

Now we do the same with the soccer team.

49+53+52+52+57+61+55+61+59+61+50+50+51+62+50+57=880

880/16=55

Now we subtract.

64.64-55≈10

Therefore, our answer is D) 10 inches

I hope this helps!

Answer 2

Hi!

Let's find the mean of both data sets.

Basketball

57 + 63 + 68 + 72 + 50 + 63 + 65 + 69 + 73 + 71 + 60 = 711

711/11 = 64.63

Soccer

49 + 53 + 52 + 52 + 57 + 61 + 55 + 61 + 59 + 61 + 50 + 50 + 51 + 62 + 50 + 57 = 880

880/16 = 55

64.63 - 55 = 9.63

The answer is D) 10 inches

Hope this helps! :)
