Answer:
The correct answer is False.
Explanation:
It is a cognitive bias that describes the common human tendency to rely too heavily on the first piece of information that is offered when making decisions: the "anchor." Also known as the "focus effect." During decision making, anchoring occurs when people use an initial piece of information to make subsequent judgments. Once the anchor is fixed, the rest of the information is adjusted around the position of the anchor incurring a bias.
For example, the starting price offered for a used car sets the standard for the rest of the negotiations, making prices lower than the starting price seem more reasonable even though they are still higher than what the car is really worth. In the same way, if you ask about the population of Ukraine: "Is it greater or less than one hundred million people?", The answers will vary, but in general they will be somewhat less than this number. However, if the question were: "Is the population of Ukraine more than or less than twenty million people?" The answers will vary, but the average of answers will not change much from the initial anchor. That is, it starts from the "anchor value" and an adjustment is made ... which is usually in the right direction but of insufficient magnitude.
Answer:
The answer to this question is a= µ=60/12=5 students/min
Explanation:
Solution
Given that:
λ=4 students / min
The Waiting time in Queue= λ /µ(µ- λ )==4/(5*(5-4))=0.8 min
The Number of students in the line L(q)= λ *W(q)= 4*.8= 3.2 students
TheNumber of students in the system L(q)= λ /(µ- λ )=4/(5-40=4 students
Then,
The Probability of system to be empty= P0= 1-P= 1-0.8= 0.2
Now,
If the management decides to add one more cashier with the same efficiency then we have
µ= 6 sec/student= 10 students/min.
so,
P= λ /µ =4/10=0.4
Now,
The probability that cafeteria is empty= P0= 1-0.4= 0.6
If we look at the above system traits, it is clear that the line is not empty and the students have to standby for 0.8 in the queue waiting to place their order and have it, also on an average there are 3.2 students in the queue and in the entry cafeteria there are 4 students who are waiting to be served.
If the management decides to hire one more cashier with the same work rate or ability, then the probability of the cafeteria being free moves higher from 0.2 to 0.6 so it suggests that the management must hire one additional cashier.
Answer:
a. What is the average annual return?
average annual return (mean) = (-4.5% + 28.1% + 12.2% + 3.7%) / 4 = 9.875%
b. What is the variance of the stock's returns?
variance = [(-4.5% - 9.875%)² + (28.1% - 9.875%)² + (12.2% - 9.875%)²) + (3.7% - 9.875%)²] / 4 = (206.64 + 332.15 + 5.41 + 38.13) / 4 = 582.33 / 4 = 145.5825
c. What is the standard deviation of the stock's returns?
standard deviation = √145.5825 = 12.06%
Answer:
$27,400 and $59,600
Explanation:
The computation of the depreciation expense and the book value using the sum of-the-years'-digits method is shown below:
Depreciation expense is
= (Purchase cost - residual value) × useful life ÷ sum of years
= ($87,000 - $4,800) × 5 years ÷ (5 + 4 + 3 + 2 + 1)
= $27,400
And, the book value is
= Purchase cost - depreciation expense
= $87,000 - $27,400
= $59,600
