The formula for calculating the Confidence Interval is as
follows:
Confidence Interval = x +- (z*s)/√N
Where:
x = mean = 10.36
z = taken from standard normal distribution table based on 95%
confidence level = 1.96
s = standard deviation = 5.31
N = sample size = 30
Substituting know values on the equation:
Confidence Interval = 10.36 +- ( 1.96 * 5.31) / √30
Confidence Interval = 8.46 and 12.26
Hence the bill of lunch orders ranges from 8.46 to 12.26.

Answer:
$1,952 (Positive NPV)
Explanation:
Year Annual CF ($) PV factor at 10.30% PV of Cash Flow ($)
1 17,000 0.90662 15,413
2 17,000 0.82196 13,973
3 17,000 0.74520 12,668
4 17,000 0.67561 11,485
5 17,000 0.61252 10,413
6 17,000 0.55532 9,441
7 17,000 0.50347 8,559
TOTAL 1.73554 81,952
Net Present Value (NPV) = Present value of annual cash flows - Initial Cost
Net Present Value (NPV) = $81,952 - $80,000
Net Present Value (NPV) = $1,952 (Positive NPV)
