Answer:
The degrees of freedom are given by:
And replaicing we got:
The 95% confidence interval would be between 26.9 and 31.1
Step-by-step explanation:
Information given
represent the sample mean
population mean
s represent the sample standard deviation
represent the margin of error
n represent the sample size
Solution
The confidence interval for the mean is given by the following formula:
(1)
And this formula is equivalent to:

Morse's monthly expenses are:
* $2,704 for fixed expenses.
* $687 for living expenses.
* $454 for annual expenses.
His total monthly expenses are:
$2,704 + $687 + $454 = $3,845
His annual total expenses are:
12 × $3,845 = $46,140
His annual net income is $46,752. Thus his annual balance is:
$46,752 - $46,140 = $612
His monthly balance is $612/12 = $51.
There is a surplus of $51
