Answer:
<u><em></em></u>
- <u><em>4.75% of the candidates takes more than two hours to learn the computer system.</em></u>
<u><em></em></u>
Explanation:
The relevant information to solve the problem is:
- 1. <em>The time it takes to learn follows a Normal distribution </em>
- 2.<em> The mean is 90 minutes</em>
- 3. T<em>he standard deviation is 18 minutes</em>
- 4. <em>The question is What proportion of candidates takes more than two hours to learn the computer system?</em>
Then, you shall calculate the Z-score and use a standard distribution table to look up the Z-score and the corresponding probability.
Repeating myself from a recent answer, "there are two types of standard distribution tables: tables that show values that represent the AREA to the LEFT of the Z-score, and tables that show values that represent the AREA to the RIGHT of the Z-score".
<u>1. First, calculate the Z-score:</u>
<u>2. Use the table that represents the area to the right of the mean to find the ratio of typists that have a Z-score greater than 1.67.</u>
Therefore, 4.75% of the candidates takes more than two hours to learn the computer system.
Answer:
Labor Efficiency Variance = $12,480 Unfavorable
Explanation:
Labor Efficiency variance calculates the capacity utilization of labor.
Formula for Labor Efficiency Variance = ( Standard Labor Hours - Actual Hours) Standard Rate
Standard Labor hours for actual output = 10,000 units 2 hours = 20,000 hours
Standard Rate = $12.00
Actual Hours = 21,040 hours
Therefore, Labor Efficiency Variance = (20,000 - 21,040) $12
= - $12,480
Since the value is negative it is unfavorable as actual hours is more than standard hours.
Answer:
knows that he is a multinational company runner or manager
Answer:
all of the above
Explanation:
Net present value is the present value of after-tax cash flows from an investment less the amount invested.
Only projects with a positive NPV should be accepted. A project with a negative NPV should not be chosen because it isn't profitable.
When choosing between positive NPV projects, choose the project with the highest NPV first because it is the most profitable. This ensures that shareholder wealth is maximised
The NPV method uses discounted cash flows. so the time value of money is considered
