Answer:
Explanation:
For example: Suppose you want to check the average working hour of employees. You may think that the average duration of an employees is 7.6 hours. You want to check this claim so you collect a sample of 20 employees and note their duration of work. (please check attached file for this, and continue)
NULL HYPOTHESIS H0:u= 7.6 HOURS
ALTERNATIVE HYPOTHESIS Ha: ≠7.6 HOURS
alpha=0.05
t= 7.765-7.6/1.25/sqrt(20)
t= 0.165/1.25/4.47
t= 0.165/0.28
t= 0.589
degrees of freedom= n-1=20-1=19
t critical = 2.09
Since t critical is GREATER than t calculated therefore we fail to reject null hypothesis H0.
From this we can conclude that We don't have enough or sufficient evidence to say that the mean working duration is different than 7.6 hours.
Answer:
$1,150.
Explanation:
First, we find what that 15% is by setting an equation:
This gives us: $150
Now, we just add that to the deposited money.
$1000 + $150 = $1,150
Hope this helps!
Answer:
b. An increase of $15 million
Explanation:
The computation of the cash impact of the change in working capital is shown below:
As we know that
Working capital = Current assets - current liabilities
So, the change in working capital is
= Increase in current assets - increased in current liabilities
= $40 million - $25 million
= $15 million
Hence, the b option is correct
Answer:
The correct answer is D. One, what goods and services will be produced? Two, how will the goods and services be produced? Three, who will receive the goods and services produced?
Explanation:
There are two questions in particular that summarize the reason for the economy:
• How do elections determine what, how and for whom goods and services are produced?
• At what point are choices made in pursuit of personal interest promoting social interest?
What, how and for whom?
Goods and services are the objects that people value and produce to meet their needs.
What? It determines the goods and services that are produced as well as the amount that is produced from each good and service.
How? Goods and services are produced using what economists call production factors.
The factors of production are the resources that companies use to produce goods and services. These factors fall into four categories:
• Earth
• Job
• Capital
Answer:
The answer is: D) Risk is a measure of the uncertainty surrounding the return that an investment will earn.
Explanation:
Investment risk refers to the probability of losing an investment. It measures the uncertainty level of earning returns from an investment.
When an investor anticipates a higher risk, he will expect higher returns. On the contrary, low risk investments (e.g. T-Bills) offer very low yields.
