Please read the attached case and use the attached date to answer these three question as Case Study Business Report (I attached example)
1. Develop a graph or table that portrays the checking
balances. What is the balance of a typical customer?
Do many customers have more than $2,000 in their
accounts? Does it appear that there is a difference in
the distribution of the accounts among the four
branches? Around what value do the account balances
tend to cluster?
2. Determine the mean and median of the checking
account balances. Compare the mean and the median balances for the four branches. Is there a
difference among the branches? Be sure to explain
the difference between the mean and the median in
your report.
3. Determine the range and the standard deviation of
the checking account balances. What do the first and
third quartiles show? Determine the coefficient of
skewness and indicate what it shows. Because Mr.
Selig does not deal with statistics daily, include a brief
description and interpretation of the standard deviation
and other measures.
