Calculate the sample standard deviation
First, calculate the mean
The sample standard deviation is then calculated using:
So, we have:
-- approximated
Answer:
6y - 3y - 7 = -2 +3
Simplify both sides:
3y -7 = 1
Add 7 to both sides:
3y = 8
Divide both sides by 3:
y = 8/3 = 2 2/3
There is only one solution.
