A drug company is considering marketing a new local anesthetic. The effective time of the anesthetic the drug company is current

ly producing has a normal distribution with a mean of 7.4 minutes with a standard deviation of 1.2 minutes. The chemistry of the new anesthetic is such that the effective time should be normally distributed with the same standard deviation, but the mean effective time may be lower. If it is lower, the drug company will market the new anesthetic; otherwise, they will continue to produce the older one. A sample of size 36 results in a sample mean of 7.1. A hypothesis test will be done at the 10% level of significance to help make the decision.

Murljashka [212]

Answer:

The correct answer is the option C: the restaurant has been around for many years and the customers have a nostalgic preference for it.

Explanation:

It is quite understood that if a restaurant has a wide number of loyal customers due to their brand recognition then that company will ultimately tend to charge a higher price to the customers because of their loyalty. However, this unique situation of loyalty may not explain completely how that business could do it when there are many other competitors around the same region, and therefore that if an explanation must be found to why the company can charge more and still remain competitive then more details of the company's strategy must be revealed.

Andru [333]

Answer:

The correct answer is Gain or loss on the sale of equipment as part of continuing operations.

Explanation:

If a gross profit on sales is generated in the process of selling an item of property, plant and equipment, but additional expenses are also incurred, the only thing that is recognized in the income statement is the net profit.

Among the accounts of the income statement, only one record is made with the net profit that occurred in the process of the sale of the asset. Although the final effect on the income statement is the same as it had under the old regulatory framework, it can be said that with that single record among the income statements, what is sought is that high gross income and expenses are not shown high, as this could distort the different financial analyzes that will be carried out at the end of the year.

Your company works with freelance writers, and Jake, your colleague, is responsible for processing the freelancers' invoices. La
trapecia [35]

Answer:

The sentence uses an active voice

In this case active voice is not appropriate

Explanation:

Mode of expression can be passive or active.

Passive voice is one that emphasises the subject or person that is receiving an action.

An active voice describes a person that is performing an action.

In this scenario Jake accidentally input $560 instead of $650 on one of the invoices. The writer hasn't contacted you about the error yet.

So the email sent should just focus on what has happened to the writer and also to proffer a solution to the problem.

Since the writer did not complain or request for information on who made the mistake, stating that it was Jake that made the error is inappropriate.

A better statement would have been - An error was made on your invoice where the figure was inputted as $560 instead of $650. This however has been rectified and the invoice forwarded to you.
