The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample (
) = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) = 
= 
= 
= 11
Hence the standard deviation is equal to 11.
If all firms only earn a normal profit in the long run, firms will develop new products or lower-cost production methods because they can innovate and possibly earn an economic profit in the short run.
Explanation:
Competition involves constant efforts by companies and executives to do more than the loss (normal gains) of new goods or by improving ways to manufacture current products at lower prices. Therefore, if businesses can invent, they will achieve short-term economic advantage.
Economic benefit encourages entry, economic losses lead to exit and firms in a highly profitable market earn little economic income in a long-term equilibrium. In an industry where inflation does not change the costs of materials (a market with a constant cost), the long-term supply curve is a horizontal line.
Answer: less than the coupon
Explanation:
When a bond that is bought at a premium of 205 is called before the bond matures by the issuer, this implies that the accelerated premium loss will have to be reflected in calculated yield to maturity.
It should also be noted that the YTC is the lowest among the yields for the premium bonds. Therefore, if the issuer calls the bond before maturity, the yield to call (YTC) realized by the investor would be less than the coupon.
Option B is correct.
Answer:
No
Explanation:
The trial balance shows the totals of all transactions that have been recorded. It has no way of knowing if there are additional transactions that have not been recorded.
Answer:
<em>c. evaluative criteria
</em>
Explanation:
Evaluative criteria are <em>when a consumer chooses a different product because of factors like value, cost, and functionality from the one they initially had in mind. </em>
It could take a little while for certain consumers to study and explore different goods before they purchase.
While some, just before they purchase, can make the decision automatically.
