The mean height of the basketball players is 80.3 inches

For given question,

we have been given the list of heights, in inches, for a sample of college basketball players.

We need to find the mean height of the basketball players.

We know that, for given sample of data

mean = sum of all observations ÷ total number of observation

First we find the sum of given heights.

78 + 83 + 82 + 78 + 78 + 80+ 81 +79+ 79 +83+ 77 +78+ 84+ 82+ 80+ 80 +82+ 84+78+ 80 = 1606

Total number of observations = 20

Using the formula of mean,

⇒ mean height = 1606/20

⇒ mean height = 80.3 inches

Therefore, the mean height of the basketball players is 80.3 inches

Among the eighth-graders in Micheal's school, 70% have siblings. The eighth-grade class is 5/6 the size of the seventh-grade cla

sladkih [1.3K]

OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:

0.7(total 8th graders) = 112

total 8th graders = 112/0.7

total 8th graders = 160

And since the number of 8th graders is 5/6 the size of the 7th grade class:

5/6(7th grade class) = 160

5(7th grade class) = 960

7th grade class = 192.
