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:
Average rate of return= 10.17
%
Geometric return = 9.23%
Explanation:
<em>Geometric average return</em>
This is compounded annual rate of return which is used to measure the performance of an asset over a certain number of years. It helps to measure the return generated by an investment taking into account the volatility .
Unlike the arithmetic average the geometric average gives an idea of the real rate taking into account of volatility
The formula below
Geometric Return =(1+r1) (1+r2) ...... (1+rn)^1/n
Geometric Average return =
(1.12× 1.19× 1.21× 0.88× 1.26× 0.95)^(1/6) - 1 =0.09233168
Geometric return =0.0923
× 100= 9.23%
Geometric return = 9.23%
Average rate of return
<em>The average return is the sum of the returns over the years dividend by the Numbers of returns</em>
Average return = sum of return / No of returns
(12% + 19% + 21% + (12%) + 26% + (5%))/6 =10.17
%
Average rate of return= 10.17
%
Geometric return = 9.23%
Answer:
The answer is a. Organizational behavior
Explanation:
Organizational behavior simply put, is the academic study of how a group of people act within an organization. The results are then utilized to make the organization operate more effectively.
Organizational behavior studies can cover areas such as job performance, job satisfaction, innovations, and leadership within an organization. The goal is simply to see how these areas can be improved, which will then lead to organizational growth.

Answer:
Firm A will buy all of the firm B's pollution permits. Each one will cost between $100 and $200.
Explanation:
The firm B will gain from the trade of pollution permits. Firm A will need higher pollution permits since it emits 100 tons of chemicals into air and the cost for eliminating each ton is $200. This cost is higher than the cost to Firm B which is $100 only. Firm A will buy all the pollution permits from Firm B and there will advantage for the Firm B to gain from the trade.
