Answer:

c. Independent samples t test

Explanation:

An independent samples t test is used in the above case. Independent samples t test are employed when comparison is between two independently groups. Independent samples t test compares the mean of two independent groups as in above to determine if there is a statistically significant difference between them for the purpose of making a decision. For example in the above scenario if there is a difference in the means, we can conclude that City A and city B residents do not travel same distance in miles

Answer:

The unemployment rate is 42.85.

Explanation:

The formula to calculate the unemployment rate is:

Unemployment Rate = (Unemployed People / Total Labor) x 100 -- (1)

where total labor is the sum of the unemployed people and employed people.

Unemployed People = 10 Retired persons + 5 stay-at home parents + 10 persons with no job + 5 persons who wanted job

Unemployed People = 30

Labor Force = Employed people + Unemployed people

Labor Force = 40 + 30

Labor Force = 70

Putting the values in equation 1,

Unemployment Rate = ( 30/ 70) x 100

Unemployment Rate = 42.85

Fynjy0 [20]

Answer:

Identification of Features Applying More to Job Order Operations, Process Operations, or Both:

Features  

1. Cost object is a process.                                  Process Operations

2. Measures unit costs only at period-end.        Process Operations

3. Uses indirect costs.                                          Both

4. Transfers costs between Work in              

   Process Inventory accounts.                            Process Operations

5. Uses only one Work in Process account.       Job Operations

6. Uses materials, labor, and overhead costs.    Both

Explanation:

The main difference between the two operations is the manner costs are accumulated.  Job operations accumulate costs for different jobs that are not similar.  Process operations accumulate costs to show the process a product passes through.  The product of a process operation is not unique like the product of a job operation.

The Morrow Company has assembled the following data pertaining to certain costs that cannot be easily identified as either fixed
Iteru [2.4K]

Answer:

$39,800

Explanation:

From the question above Morrow company has decided to use the measuring cost function method to find its total cost

- $68,400 is the highest cost and $37,600 is the lowest cost

- 6,000 is the highest number of hours and 3,200 is the lowest

The first step is to calculate the cost driver. Let's use the alphabet c to represent the cost driver

(68,400-37,600) / (6,000-3,200)

c = 30,800/2,800

c= $11

Cost driver= $11

The next step is to find the fixed cost. Let's use the alphabet f to represent the fixed cost

68,400= f + ( 11×6000)

68,400= f + 66,000

f= 68,400-66,000

f= $2,400

Fixed cost= $2,400

The final step is to calculate the cost function

Cost function= fixed costs+variable costs×number of units

Fixed cost= $2,400

Variable cost= $11

Number of units= 3,400 hours

= 2,400+(11×3,400)

= 2,400+ 37,400

= $39,800

Hence the total cost at an operating level of 3,400 hours is $39,800
