Using confidence interval concepts, it is found that:
a) The point estimate is the sample mean.
b) The confidence interval is:
c) If $1411 is between the bounds of the interval yes, otherwise no.
--------------

--------------
Item b:
- In the spreadsheet, it is possible to find the <em>standard deviation for the sample</em>, thus, the t-distribution is used.
- The confidence interval will be given by:
In which:
- is the sample mean.
- T is the critical value, from the t-distribution, with a two-tailed area of and n-1 degrees of freedom.
- s is the standard deviation for the sample.
- n is the sample size.
--------------
Item c:
We have to check if 1411 is between and .
- If it is, the interval includes the National Average, otherwise, it does not.
