Answer:
The test statistic t of the sample is -0.804.
There is sufficient evidence to ascertain that the average number of years of work experience of MBA applicants is less than 3 years.
Explanation:
Null hypothesis: The average number of years of work experience of MBA applicants is 3 years.
Alternate hypothesis: The average number of yet of work experience of MBA applicants is less than 3 years.
Test statistic (t) = (sample mean - population mean) ÷ sd/√n
sample mean = 2.57
population mean = 3
sd = 3.67
n = 47
t = (2.57 - 3) ÷ 3.67/√47 = -0.43 ÷ 0.535 = -0.804
Assuming a 5% significance level
degree of freedom = n - 1 = 47 - 1 = 46
The critical value corresponding to 46 degrees of freedom and 5% significance level is 2.013.
Conclusion:
Reject the null hypothesis because the test statistic -0.804 is less than the critical value 2.013.
The years of work experience of MBA applicants is less than 3.
Answer:
Lucky event
Explanation:
In the investments market a true measure of market efficiency is to get a track record of positive outcome from investors over time.
The lucky event problem occurs when an investor makes a profit on investment not because of how efficient a market is or by a logical procedure, but rather by chance.
In the given scenario Keyes put all his money in one stock that doubled in 3 months.
However this was not replicated among other investors who made similar vets on other stocks and lost.
This is an exams of lucky event problem in determining market efficiency.
Answer:
C. Variable inflation is associated with high transaction costs
Explanation:
Because of uncertainty about future inflation, it may not uncertain relative to its price change. Therefore, option A is not correct.
In order to maximize financial position, inflation harms borrowers and helps lenders, so option B is also incorrect.
Option C is correct because variable inflation is associated with high transaction costs in order to maximize the financial position. For example, if the inflation rate is 5% during first quarter, the price level is not much to disrupt the financial position. Again, in the next quarter, if the inflation rate changes to 4%, the position will be effective more. However, if it increases, it will not affect too much.
Answer:
For both 10,000 units and 20,000 units, the best alternative is Vendor B
Explanation:
Using the information provided in the question, we can write the following:
Annual Volume of 10,000 units
Internal Alternative 1
Variable costs = 170,000 (we multiply the variable cost per unit by total units)
Fixed costs = 20,000
Total costs = 370,000
Internal Alternative 2
Variable costs = 140,000
Fixed costs = 240,000
Total costs = 380,000
Vendor A
Total cost = 200,000 (we simply multiply the price by the quantity)
Vendor B
Total cost = 180,000
Vendor C
Total cost = 190,000
The cheapest option is Vendor B
Now for the 20,000 units:
Internal Alternative 1
Variable costs = 340,000
Fixed costs = 200,000
Total costs = 540,000
Internal Alternative 2
Variable costs = 280,000
Fixed costs = 240,000
Total costs = 520,000
Vendor A
Total cost = 400,000
Vendor B
Total cost = 360,000
Vendor C
Total cost = 380,000
Therefore, Vendor B is once again, the cheapest alternative.
