Game A, as   the standard deviation is higher and, thus offers fewer choices in outcomes

Question 11 2 pts

Say a business wants to know if each salesperson is equally likely to make a sale. The company chooses 5 salespeople and gathers information on their sales experiences. What assumption must be made for this study’s probability results to be used in future binomial experiments?

Yes, the   probability of six or less having straight stitching is unusual

No, the   probability of six or less having straight stitching is not unusual

No, the   probability of exactly six have straight stitching is not unusual

Yes, the   probability of exactly six having straight stitching is unusual

Question 13 2 pts

A soup company puts 20 ounces of soup in each can. The company has determined that 97% of cans have the correct amount. Which of the following describes a binomial experiment that would determine the probability that a case of 24 cans has all cans that are properly filled?

n=20, p=0.97,   x=20

n=24, p=0.97,   x=1

n=24, p=0.97,   x=24

n=20, p=0.97,   x=20

Question 14 2 pts

A supplier must create metal rods that are 18.1 inches width to fit into the next step of production. Can a binomial experiment be used to determine the probability that the rods are the correct width or an incorrect width?

No, as the   probability of being about right could be different for each rod selected

Yes, all   production line quality questions are answered with binomial experiments

No, as there   are three possible outcomes, rather than two possible outcomes

Yes, as each   rod measured would have two outcomes: correct or incorrect

Question 15 2 pts

In a box of 12 pens, there is one that does not work. Employees take pens as needed. The pens are returned once employees are done with them. You are the 5th employee to take a pen. Is this a binomial experiment?

No, binomial does not include systematic selection such as “fifth”

No, the probability of getting the broken pen changes as there is no replacement

Yes, you are find the probability of exactly 5 not being broken

Yes, with replacement, the probability of getting the one that does not work is the   same

Question 16 2 pts

Forty-two percent of employees make judgements about their co-workers based on the cleanliness of their desk. You randomly select 7 employees and ask them if they judge co-workers based on this criterion. The random variable is the number of employees who judge their co-workers by cleanliness. Which outcomes of this binomial distribution would be considered unusual?

1, 6, 7

1, 2, 6, 7

0, 6, 7

0, 1, 2, 7

Question 17 2 pts

Eighty-one percent of products come off the line within product specifications. Your quality control department selects 15 products randomly from the line each hour.

Fewer than 12

Fewer than 9

Fewer than 11

Fewer than 10

16) The partial productivity of overhead resources can be measured by considering the cost driver as ________.

A) budgeted input

B) the denominator

C) the fixed input

D) the numerator

 

17) Which of the following statements is true of productivity measures?

A) Partial productivity and total factor productivity measures  never work best together.

B) Partial productivity explicitly considers gains from using fewer physical inputs as well as substitution among inputs.

C) All productivity measures are physical measures lacking financial content.

D) Total factor productivity considers the trade-offs across various inputs based on current input prices.

18) ________ is an example of a total factor productivity measure.

A) The number of units produced per month

B) The number of units produced per machine hour

C) The number of units produced per labor hour

D) The number of units produced per dollar of input cost

 

19) Total factor productivity explicitly considers gains from using fewer physical inputs as well as substitution among inputs.

 

20) Partial productivity and total factor productivity measures work best together because both measures have the same kind of strengths and weaknesses.

 

21) One problem with total factor productivity revolves around the measurement of combined productivity of all inputs.

 

22) Productivity describes the relationship between different quantities of inputs consumed and the quantities of output produced.

23) Power Company has been unhappy with the financial accounting variances that its cost accounting system has been producing, because its managers believe that there is more to evaluating an operation than just examining accounting numbers. Therefore, it has started gathering data to assist in the examination of nonfinancial results of operations. The following information relates to the manufacture of remote control units for televisions, radios, and stereo components:

 

20112012

Remote control units produced and sold80,000100,000

Direct manufacture labor-hours12,00013,200

Direct materials used (sets)80,600100,500

Direct manufacture cost per hour$18$20

Direct materials cost per set$31$32

 

Required:

a.What is the partial productivity of direct materials for each year?

b.What is the partial productivity of direct manufacturing labor for each year?

c.Did each area improve between 2011 and 2012? Explain.

d.What will be the projected direct material and labor needs for 2013 if remote control units increase by 12,000 units, assuming Power Company applies the constant returns to scale technology?

24) Grader Company manufactures road graders. Because its managers all have engineering backgrounds, they prefer nonfinancial information for their decision-making models. Therefore, they require the accountants gather data to assist in the examination of nonfinancial results of operations. The following information relates to the manufacture of a paver:

 

20112012

Units produced and sold6,8005,600

Direct manufacture labor-hours136,000115,200

Direct materials used (tons)29,00024,400
