Answer:
The upper limit is 10.1
The lower limit is 9.91
Explanation:
Given that:
The mean fill level (μ) = 10.01 ounces,
Standard deviation (σ) = 0.25 ounces
Number of sample bottles (n) = 20
The limits of the sample mean = 92% = 0.92
α = 1 - 0.92 = 0.08
The z value of 0.04 is the same as the z value of 0.46 (0.5 - 0.04). From the probability distribution table:
The margin of error (e) is given by:
The upper limit = μ + e = 10.01 + 0.1= 10.1
The lower limit = 10.01 - 0.1 = 9.91
Answer:
(A) 1,200 Margin of Safety_{units}
(B) 330,000 Margin of Safety_{usd}
(C) Margin of Safety 40% of Sales
Explanation:
(A)
275 - 150 = <u>125 CM per unit</u>
3,000 - 1,800 = 1,200 Margin of Safety_{units}
HOW? we Calculate the contribution per unit. Then the BEP in units and with that the margin of safety in units.
(B)
125/275 = 0.45454545 = <u>5/11 CM ratio</u>
225,000/(5/11) = 495,000 BEP USD
825,000-495,000 = 330,000 Margin of Safety_{usd}
HOW? we Calculate the contribution ratio by dividing CM over sales. Then the BEP in dollars and with that the margin of safety in dollars.
<em><u>Important:</u></em> When posible to avoid rounding errors express as fraction iof posible
(C)
Margin of Safety 40%
