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
