<u>Answer:</u>
<u>If there is 1 hour of production: </u>
Cars produced by Japan = 5/8 = .625 cars
HD TV produced by Japan = 15/10 = 1.5 HD TVs
Further,
Cars produced by US = 5/6 = .83 cars
HD TV produced by US = 15/5 = 3 HD TVs
So,
Opportunity cost of a car for Japan = 1.5/.625 = 2.4 units of HD TVs
Opportunity cost of car for US = 3/.83 = 3.61 units of HD TV
Since, Japan has lower opportunity cost of producing cars, so Japan has comparative advantage in producing cars.
Opportunity cost of a HD TV for Japan = .625/1.5 = .42 units of car
Opportunity cost of a HD TV for US = .83/3 = .28 units of car
Since US has lower opportunity cost of producing HD TVs, so US has comparative advantage in producing HD TVs.
Answer: The minimum number of students you need if you want the margin of error to be 5% IS 278.
Explanation:
Cochran’s Sample Size Formula gives the minimum number of students as 
Where:
e is the desired level of precision (i.e. the margin of error),
p is the (estimated) proportion of the population which has the attribute in question and q is 1 – p.
The z-value for 95% confidence interval is found to be 1.96 in a Z table.
Assuming that half of the teenagers favor the elimination of a curfew: this gives us maximum variability. So p = 0.5 and q=0.5.
Then 
Rounding up, 
But considering that 1000 is a small population, we can modify the sample size we calculated above formula by using this equation:
Where s is the adjusted sample size, n is the original sample size we calculated and N is the population size.

I think it's common terms of reference
<span>Major sales management tasks include setting objectives in concrete, adjusting the size of the sales force to meet changes in the firms' marketing plan and the marketing environment, attracting and hiring effective salespersons, developing a training program, formulating a fair and adequate compensation plan, motivating salespersons to keep productivity high, defining sales territories and determining scheduling and routing of the sales force, and evaluating the operation holistically.
These are the tasks that sales managers are typically given in their role. Though they can vary depending on company and how many people they have to help and delegate tasks to, this is a good guideline of their common roles.</span>
