The complete question is as follows:

The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?

Answer: The 95% confidence interval about the mean is $Confidence interval = 107.84 \leq \mu \leq 116.16$ .

The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.

We follow these steps to arrive at the answer:

Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.

The formula for the confidence interval about the mean is:

$Confidence interval = \overline{X}\pm Z*\frac{\sigma}{\sqrt{n}}$

In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.

The Critical Value of Z at the 95% confidence level is 1.96.

Substituting the values in the question in the equation above we have,

$Confidence interval = \112\pm 1.96*\frac{15}{\sqrt{50}}$

$Confidence interval = \112\pm 4.157787873}$

$Confidence interval = 107.8422121 \leq \mu \leq 116.1577879$

scoray [572]

Answer:

The correct answer is C. Is top management committed to the study?

Explanation:

Market research is the process that includes the actions of identification, collection, analysis and dissemination of information with the purpose of improving marketing decision making. Its implementation occurs basically for two reasons:

1. to solve problems, for example, determine the potential of a market.

2. to identify problems, for example, to know why a product does not have the expected consumption. In essence, it seeks to meet the customer thus complying with the first premise of marketing.

That is why managers and researchers continually focus on the search for those practices that will allow them to improve the organization and direction of their processes and therefore increase their likelihood of success.

Fey Corporation manufactures two models of office chairs, a standard and a deluxe model. The following activity and cost informa

alekssr [168]

Answer:

a) Standard WIP 75,000 debit

factory overhead 75,000 credit

b) applied to deluxe model 28 setups x $ 400 = $ 11,200

c) total overhead to deluxe: 35,200

Explanation:

$\frac{Cost\: Of \:Manufacturing \:Overhead}{Cost \:Driver}= Overhead \:Rate$

expected overhead: 120,000

total labor hours: 375 + 22 = 600

overhead rate: 120,000 / 600 = 200

applied to Standard model: 375 hours x $ 200 = 75,000

overhead cost for setups: $ 20,000

total setups (cost driver) 22 + 28

activity rate: $ 20,000 / 50 setups = $ 400

applied to deluxe model 28 setups x $ 400 = $ 11,200

overhead cost for component: $40,000

total components: 8 + 12 = 20

activity rate: 40,000 / 20= 2,000

applied to deluxe model: 12 x 2,000 = 24,000

<u>Overhead cost into deluxe model under ABC:</u>

setup overhead applied to deluxe model 28 setups x $ 400 = $ 11,200

component overhead applied to deluxe model: 12 x 2,000 = 24,000

Total: 35,200
