Answer:

The answer is 100%

Explanation:

we are given the mean which is $78 which is the average value of the data therefore this tells us most values are collectively around this bill and we also know the standard deviation of the cellphone bill which is $10 now we check the possibilities of x which is the cellphone bill being around these values so if x>$78+$10 , where x>$88 as we know the standard deviation is the measure of dispersion of data from the mean then we will see if x<$68 also then we'll find the probability where $68>x>$88 therefore if we sum these whole probabilities they will give us 1 which means it is certain but not impossible to find values that are $102>x>$54 which we see by the above numbers that approximately 1 is the probability which is 100%.

Charles Lin has just been hired by Frederick Company to replace a sales representative who is retiring after 40 years with the c
NISA [10]

Answer:

The answer is: B) Charles is starting from almost scratch developing a prospect and customer base and may lose some current customers because he does not know about them.

Explanation:

Obviously Charles doesn't know the customers the old sales representative had and three weeks may not be enough time for Charles to get to know them and gather enough information about them either.

So basically, Charles is starting from scratch and needs to develop his own customer database. Doing so will consume time and effort, and possibly Charles will lose some sales because of this. Eventually he will need to catch up and probably match and even exceed the previous salesman's sales records.

When testing a new​ treatment, what is the difference between statistical significance and practical​ significance? can a treatm
photoshop1234 [79]
1. For a result to be statistically significant means that the probability of the results observed been due to chance is very low or impossible. For a result to be statiscally significant means that the differences observed between the experimental group and the control group of the experiment is not  due to chance or sampling errors.
Practical significance refers to how practical it is to convert a result observed in the laboratory to use in real world scenario. The difference observed between two variables in an experimental set up may be so small that it may not be worth it to produce it on a large scale for human use.
Thus, the difference between statistical and practical significance is that statistical significance indicates the difference between two variables while practical significance determines if the results is worth been reproduce on large scale.
2. YES, a treatment can have statistical significance but have no practical significance. This means that, even though the treatment is effective, due to some reasons it is not worth it or practical to produce it on a large scale.

NeTakaya

Answer:

The correct answer is letter "B": Utilitarianism.

Explanation:

Utilitarianism is a philosophical doctrine that emphasizes the maximization of the use of goods for the greatest number of people available in a society. The most relevant characters proposing this idea were British philosophers Jeremy Bentham (1748-1832) in "<em>Introduction to the Principles of Morals and Legislation</em>" (1789) and John Stuart Mill (1806-1873) in "<em>Utilitarianism</em>" (1863).

Then, <em>utilitarianism could be implemented to implement cost-benefit analysis and risk assessment to weigh all of the social benefits and costs of a business.</em>

CaHeK987 [17]

Answer:

The company should accept the idea reason been that the profit will increase by $24,000

Explanation:

Calculation to determine What should the company do

First step

Increased CM = [10,750 x (27+(40-45))]- (10,000 x 27)

Increased CM = [10,750 x(27+5)]- (10,000 x 27)

Increased CM = (10,750 x 32) - (10,000 x 27)

Increased CM = $344,000-$270,000

Increased CM = $74,000

Now let calculate the profit

Profit =$74,000-$50,000

Profit=$24,000 Increase

Therefore based on the above calculation The company should accept the idea reason been that the profit will increase by the amount of $24,000
