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.
