The first step is to calculate the mean of the data provided.

k is a number of points in our data set.
The mean for our data set is

.
Now we need to find the range associated with confidence level required.
Z score associated with a confidence level of 80% percent is 1.28.
We know that our range has to be

in order for us to be 80% confident in our result. As the confidence level rises z score associated with it also rises. This makes sense because the broader your range is more confident you are that measurement will fall within that range.
The final answer would be:
1. Determine the total cost of the program (tuition, fees, books, cost of living, etc)
2. Determine how much of this they will have to save up for (aka the amount not covered by taking out student loans)
3. Break down that total amount into periodic savings deposits. So if you need $10,000 and you have 4 years, make a plan to save $2,500 a year.
