Answer:
a) 15 to 35 approximately 95%
(b) 10 to 40 approximately almost all
(c) 20 to 30 approximately 68%
Explanation:
The data have a bell-shaped distribution which means the data is equally distributed on both sides of the mean.
We have the mean at 25 and a standard deviation of 5 which means that the interval is for each of the values of 5 .
The mean would be u and
The first value would be u ±σ = 25 ± 5= 20 and 30 (68 % )
The second value will be u ± 2σ= 25± 10 = 15 and 35 (95%)
The third value will be u ± 3σ= 25 ± 15 = 10 and 40 (99.7 % almost all)
In the figure below the light blue region gives u ±σ on both sides of the mean
, dark blue gives u ± 2σ values on both sides of the mean and grey gives
u ± 3 σ values on both sides of the mean.
It is obvious that 68 % of the data is contained in the u ±σ light blue region, 95 % of the data in the u ± 2σ dark blue including light blue and 99.7 % in the u ± 3σ all colored regions.

Answer:
economic rent of $65,000
Explanation:
Economic rent is the amount of money paid in excess to a factor of production in excess of what is socially optimum
Economic rent = $150,000 - $85,000 = $65,000
Accounting profit= total revenue - explicit cost
Total revenue =price x quantity sold
Explicit cost includes the amount expended in running the business. They include rent , salary and cost of raw materials
Economic profit = accounting profit - implicit cost
Implicit cost is the cost of the next best option forgone when one alternative is chosen over other alternatives
Without the regulation, economic profit would be driven to zero.
Answer:
$936.33 Million
Explanation:
Current sales = $525 millions
Growth rate = 7.5%
Number of years = 10 years
Sales after 8 year = Current sales x 
Sales after 8 year = $ 525 million x 
Sales after 8 year = $ 525 million x 
Sales after 8 year = $ 525 million x 
Sales after 8 year = $ 525 million x 1.783477826
Sales after 8 year = $ 936.33 million
