Answer:
represent the sample mean
represent the sample deviation
n = 68 represent the sample size
Since the sample size is large enough n>30 we have enough evidence to conclude that the normal approximation for the sample mean makes sense. And the distribution for the sample mean would be given by:

Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Solution to the problem
For this case we have the following data given:
represent the sample mean
represent the sample deviation
n = 68 represent the sample size
Since the sample size is large enough n>30 we have enough evidence to conclude that the normal approximation for the sample mean makes sense. And the distribution for the sample mean would be given by:

Answer: B. $438
Explanation:
Correspondence Cost = Number of letters * Predetermined cost of correspondence
Predetermined cost of correspondence = Allocated cost/ Allocated base
= 14,000/1,600 letters
= $8.75 per letter
Northeast Office used 50 letters for correspondence.
Cost = 8.75 * 50
= $437.50
= $438
Answer: b. select appropriate corporate-level strategies
Explanation:
Prior to setting pricing options for its products to maximize profit, a company must select appropriate corporate-level strategies.
This is necessary in order to ensure that the strategies aligns with what the organization is willing to do in order to achieve its profit maximization goal.
Answer:
The $1,200,000 should be accounted for in Grove’s special revenue funds
Explanation:
Special revenue fund: The special revenue fund is a fund that is introduced by the government to collect the money from the public. It is made to fulfill the need for specific purposes/ projects.
The computation of special revenue funds is shown below:
= Income received for providing the meals to the needy people + financing of sales tax with respect to tourist facilities maintenance in the shopping district
= $300,000 + $900,000
= $1,200,000
