It is important to know that the sample would be the starters and the population is all members.
So, let's use the mean formula to find the mean sample
Where n = 21.
Now, we have to add all the heights of the starter players.
Then, we divide
Therefore, the mean sample is 78 inches.
Now, let's find the population mean using all team data instead
Where N = 35. Let's do the same process.
Therefore, the mean population is 76.83 inches.
