the county released data about how many schools there are in each town. schools in each town what is the mean of the numbers?
Answer
Explanation:
Step1: Identify the data values
The number of schools in Marion is 9, in Ashland is 4, in Greenwood is 10, in Columbia is 8, and in Springfield is 4.
Step2: Calculate the sum of data values
$9 + 4+10 + 8+4=35$
Step3: Determine the number of data - points
There are 5 towns, so $n = 5$.
Step4: Calculate the mean
The mean $\bar{x}=\frac{\text{Sum of data values}}{\text{Number of data - points}}=\frac{35}{5}=7$
Answer:
