Suppose you are interested in studying whether scent affects spatial reasoning abilities. You decide to test spatial reasoning u

sing completion time scores for the paper-folding test with five people, repeating the test on each person with three different scents (cinnamon, lavender, and peppermint). In this experiment, the null hypothesis is that:
a. The completion time mean for at least one scent is different from another
b. There are no individual differences in the completion time means
c. There are no differences in the mean completion times among the scents compared
The factor of interest is the ___. and the dependent variable is the ___.

Answer: 1. c. There are no differences in the mean completion times among the scents compared

2. Scent; Completion Time

Explanation:

The Null Hypothesis of a research is that hypothesis which you aim to disprove because it holds that no significant relationship between the variables being researched exists.

In this scenario you are studying whether scent affects spatial reasoning abilities.

The Null Hypothesis will.be that which states that there is no relationship between scent and spartial reasoning therefore there will be no differences in the mean completion times among the scents compared.

The factor of interest is the variable that is being changed to examine a difference making it the SCENT in this scenario.

The dependent variable changes due to the Factor of Interest so it is the COMPLETION TIME.

Bonner Corp.'s sales last year were $415,000, and its year-end total assets were $355,000. The average firm in the industry has
koban [17]

Answer:

$182,083

Explanation:

The computation of the total assets by considering the total assets turnover is shown below:

Total assets turnover = Sales ÷ total assets

2.4 = $415,000  ÷ total assets

So, the total assets equal to

= $415,000 ÷ 2.4

= $172,917

So, the assets is reduced by

= Year-end total assets - calculated assets

= $355,000 - $172,917

= $182,083

Dayna’s Doorstops, Inc. (DD) is a monopolist in the doorstop industry. Its cost is C  100  5Q  Q2, and demand is P  55  2Q.
Sauron [17]

Answer:

Explanation:

Given the following data about Dayna's Doorstep Inc(DD) :

Cost given by; C = 100 - 5Q + Q^2

Demand ; P = 55 - 2Q

A.) Set price to maximize output;

Marginal revenue (MR) = marginal cost (MC)

MR = taking first derivative of total revenue with respect to Q; (55 - 2Q^2)

MC = taking first derivative of total cost with respect to Q; (-5Q + Q^2)

MR = 55 - 4Q ; MC = 2Q - 5

55 - 4Q = 2Q - 5

60 = 6Q ; Q = 10

From

P = 55 - 2Q ;

P = 55 - 2(10) = $35

Output

35(10) - [100-5(10)+10^2]

350 - 150 = $200

Consumer surplus:

0.5Q(55-35)

0.5(10)(20) = $100

B.) Here,

Marginal cost = Price

2Q - 5 = 55 - 2Q

4Q = 60 ; Q = 15

P= 55 - 2(15) = $25

Totally revenue - total cost:

(25)(15) - [100-(5)(15)+15^2] = $125

Consumer surplus(CS) :

0.5Q(55-25) = 0.5(15)(30) = $225

C.) Dead Weight loss between Q=10 and Q=15, which is the area below the demand curve and above the marginal cost curve

=0.5×(35-15) ×(15-10)

=0.5×20×5 = $50

D.) If P=$27

27 = 55 - 2Q

2Q = 55 - 27

Q = 14

CS = 0.5×14×(55 - 27) = $196

DWL = 0.5(1)(4) = $2

A mail-order house uses 18,000 boxes a year. Carrying costs are 60 cents per box a year, and ordering costs are $96. The followi
LuckyWell [14K]

Answer:

Explanation:

Given that:

A mail-order house uses 18,000 boxes a year.

Carrying costs are 60 cents per box a year =$0.60

and ordering costs are $96.

Determine:

A. The optimal order quantity.

The optimal order quantity can be calculated by using the formula:

Q_o = \sqrt{\dfrac{2DS}{H}}

Q_o = \sqrt{\dfrac{2*18000*96}{0.60}}

Q_o = \sqrt{\dfrac{3456000}{0.60}}

Q_o = \sqrt{5760000}

Q_o = 2400 \ boxes

B. The number of orders per year.

of boxes: 1,000-1,999 Price per box: $1.25

of boxes: 2,000- 4,999 Price per box: $1.20

of boxes: 5,000- 9,999 Price per box : $1.15

of boxes: 10,000 or more Price per box : $1.10

SInce 2400 boxes lies within ''of boxes: 2,000- 4,999 Price per box: $1.20 ''

Total cost = Carrying cost + ordering cost + Purchasing cost

Total \ cost =(\dfrac{Q}{2} )H +(\dfrac{D}{Q}) S+PD

Total \ cost =(\dfrac{2400}{2} )0.60 +(\dfrac{18000}{2400}) 96+1.20*18000

Total cost  = ( 1200) 0.60 + 7.5(96) + 1.20(18000)

Total cost  = 720 + 720 + 21600

Total cost  =  $ 23040

If the order size is 5000, the price per box will be 1.15

Total \ cost =(\dfrac{Q}{2} )H +(\dfrac{D}{Q}) S+PD

Total \ cost =(\dfrac{5000}{2} )0.60 +(\dfrac{18000}{5000}) 96+1.15*18000

Total cost = 2500 (0.60) + 3.6 (96) + 20700

Total cost = 1500 + 345.6 + 20700

Total cost = $22545.6

If the order size is 10000 , the price per box will be 1.10

Total \ cost =(\dfrac{Q}{2} )H +(\dfrac{D}{Q}) S+PD

Total \ cost =(\dfrac{10000}{2} )0.60 +(\dfrac{18000}{10000}) 96+1.10*18000

Total cost = 5000 (0.60) + 1.8(96)  + 19800

Total cost =  3000 + 172.8 + 19800

Total cost = $22972.8

From the three total cost, the least minimum cost of ordering is: 5000

So; the number of orders per year = total number of boxes per year/ boxes per order

the number of orders per year = 18000/5000

the number of orders per year = 3.6 orders per year
