Answer:
The expected value of the proposition is $2.50.
Explanation:
When a coin is tossed two times, the following is the sample space (S)
S = {HT,TH,TT,HH}
Using the information in the question, we can derive the following win/loss table:
S Probability Payoff
TH 1/4 -$30
HT 1/4 -$30
TT 1/4 -$30
HH 1/4 $100
The expected value (E) can now be calculated as follows:
E = Sum of (Probability * Payoff) = (1/4 * ($-30)) * (1/4 * ($-30)) * (1/4 * ($-30)) = (1/4 * $100) = ((1/4) * (-30)) + ((1/4) * (-30)) + ((1/4) * (-30)) + ((1/4) * 100) = $2.50
Answer:
False
Explanation:
Hawthorne is a researcher who tried to analyse and examine employee's behaviour and what motivates them to work more hard. The above statement is false because according to Hawthorne study employee's motivation is not related to incentives. Hawthorne concluded that an employee's motivation is strongly linked with their relationship with the manager and the supervisor. A healthy Employee – supervisor relationship motivates and encourage them to carry out directives.
Answer:
a. The Geometric average return is 1.72%
b. The Arithmetic average return is 1.75%
c. The Dollar weighted average return is 2.61%
Explanation:
a) In order to calculate the time-weighted geometric average return we would have to calculate first the Holding period return as follows:
Holding period return = (200 - 190) / 190 = 5.263%
Hence, Geometric average return = (1 + .05263)^(1/3) - 1 = 1.72%
b) To calculate time-weighted arithmetic average return we have to make the following calculation:
Arithmetic average return = 5.263% / 3 = 1.75%
c) To calculate time-weighted arithmetic average return we would have to make the following calculation:
Dollar weighted average return=-190*3 + 200/(1+r) + 200/(1+r)^2 + 200 / (1+r)^3 = 0
= 2.61%
