Answer: E.53

Explanation:

From the above information, the formula for due date is given below.

DUE DATE = Expected Completion Time + (Z * Standard Deviation)

A confidence level refers to the percentage of all possible samples that can be expected to contain the true population parameter. It is computed according to a random sample from the population and most times always associated with a certain confidence level that is a probability, usually presented as a percentage. The 90% says that 90% will include the true mean but 10% won't.

A Z-score is referred to as a numerical measurement that is made use of in statistics of a value's relationship to the mean (that is average) of a group of values, measured in terms of standard deviations away from the mean.

Expected time = 40

Confidence interval = 90 = Z VALUE of 1.282

Standard Deviation= 10

DUE DATE = 40 + (1.282 * 10) = 53days

= 40+ 12.82

=52.82

Approximately 53

Therefore,the time in days is 53 days.

Answer:

E- 53

Explanation:

FORMULA:

DUE DATE = EXPECTED COMPLETION TIME + (Z * STDEV)

Expected time = 40

CONFIDENCE INTERVAL = 90 = Z VALUE OF 1.282

STANDARD DEVIATION = 10

DUE DATE = 40 + (1.282 * 10) = 53

A manager doing performance appraisals gives more weight to recent employee behaviors than to behaviors of 6 or 9 months earlier
stiv31 [10]

Answer:

The correct answer is letter "B": availability.

Explanation:

Availability bias or availability heuristic refers to individuals tending to relate the easiest judgment they can recall about a certain matter as its most suitable metric and even a metric that could predict future behavior on that topic. This happens because those people make assumptions based on what they can remember of that matter which might not be necessarily the most accurate input about it.

Therefore,<em> if a manager is measuring performance only placing focus on employees' recent and not past behavior, the manager is implementing availability bias.</em>

You want to invest in a project in Canada. The project has an initial cost of C$828,000 and is expected to produce cash inflows
tamaranim1 [39]

Answer:

C$24,650

Explanation:

initial cost C$828,000

net cash flows for years 1, 2 and 3 C$355,000

discount rate 12%

the net present value in C$ = C$355,000/1.12 + C$355,000/1.12² + C$355,000/1.12³ - C$828,000 = C$316,964 + C$283,004 + C$252,682 -  C$828,000 = C$24,650

Since we are asked to determine the NPV in Canadian dollars, all we need to do is carry out the same calculations as if they were any other currency. We do not need to make any adjustments due to the exchange rate between US dollars and Canadian dollars.
