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?

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!

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! :)
