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: $147
Explanation:
First find what 40% of $245.00 is:
= 40% * 245
= $98.00
The boots are sold at a discount of 40%. This means that 40% - which is $98 - was deducted from the value.
The selling price is therefore:
= 245 - 98
= $147
Answer: $80
Explanation:
Since the fixed costs are $180,000 and variable costs are $540,000, then the total cost will be:
= Fixed cost + Variable cost
= $180000 + 540000
= $720000
Since there are 9000 units, then the unit sales price will be:
= $720000 / 9000
= $80
The unit sales price is $80
Answer:
Rebel
Explanation:
Burton Clark and Martin Trow, the two sociologists described about the four types of college subcultures.
1) Collegiate
2) Academic
3) Vocational
4) Rebel
Britt has all the characteristics of Rebel subculture, that is being deeply involved with ideas from the classroom and wider society of art, literature, and politics. They are aggressive nonconformism, and find critical detachment from the college they attend and from its faculty like Britt consider her professors ideas as outdated.
(a) Discount amount = Face value - Price of t-bills = $1,000-$996 = $4
(b) Amount received at maturity = Face value = $1,000 (Note: T-bills are guaranteed and thus one of the safest investment).
(c) Current yield, R = Discount amount/Face value * 360/t, where t = 52 weeks = 360 days.
Then,
R = (4/1000)*(360/360)*100 = 0.4%
