In 2014, a group of students was interested in investigating prices of rental accommodation in suburbs of Brisbane that are close to the CBD and collected information on a total of 200 randomly chosen dwellings in four inner western suburbs. A subset of this data, relating to rental apartments in these suburbs is included below. The variables are:

Per week: weekly rental price for the apartment ($);

Bedrooms: number of bedrooms in the apartment;

Sqm: size of the apartment (m²)

Furnished: whether the apartment was furnished or not (yes/no).

The values are;

Question 3)

The students were interested in the proportion of rental apartments in these suburbs that were leased as furnished apartments, and whether this varied with the number of bedrooms in these apartments. To investigate further whether the proportions of furnished apartments differ between apartments with different numbers of bedrooms, it is useful to test formally whether the number of bedrooms in an apartment and whether it is furnished or not are independent.

a) Test whether the number of bedrooms in an apartment and whether it is furnished or not is independent.

b) State the null hypothesis, the relevant form of the test statistic and the approximate distribution of the test statistic for carrying out this text.

c) Perform a hypothesis test with using α = 0.05, of whether the proportions of furnished apartments vary across number of bedrooms, that is, whether the furnishing status of an apartment is independent of the number of bedrooms in the apartment.

Include the Following:

i) The table of expected frequencies

ii) The observed value of the test statistic

iii) The relevant degrees of freedom for the distribution of the test statistic

IV) The resulting p-value for the test, or a rejection region

Conclude the test by interpreting the p-value (or rejection region and your observed test statistic) in terms of the original question discussed above

Pls do this question with R code !!!!

Expenses:

Selling expense. $1,863,000

Administrative expense. 1,863,000

Total expense. 3,726,00

Income from operations. $93,150

The division of cost between fixed and vaieable is as follows:

Variable. Fixed

Cost of goods sold. 70%. 30%

Selling expense. 75%. 25%

Administrative expense. 50%. 50%

Management is considering a plant expansion program that will permit an increase of $621,000 in yearly sales. The expansion will increase fixed cost by $62,100, but will not affect the relationship between sales and variable cost.

Required:

1. Determine the total variable cost and the fixed ost.for the current year. Enter the finale answers rounded to. The nearest dollar.

Total variable cost $

Total fixed cost $

2.determine (a) the unit variable cost and (b) the unit contribution margin for the current year.enter the finale answer rounded to two decimal places.

Unit variable cost $

Unit contribution margin $

3. Compute the break-even sales (units) for the current year. Enter the finale answers rounded to the nearest whole number.

4. Compute the break-energy sales ((units) under the proposed program for the following year. Enter the finale answer rounded to the nearest whole number

5.determine the amount of sales (units) that would be necessary under the proposed program to realize the $93,150 of income from operations that was earned in the current year. Enter the final answers rounded to the nearest whole numbe.

6. Determine the maxi um income from operations possible with the expanded plant. Enter the finale answer rounded to the nearest dollar.

7. If the proposed is accepted and sales remain at the current level, what will the income or loss from operations be for the following year? Enter the final answer rounded to the nearest dollar.

8. Based on the data given, would you maintain the current income from operations would be below the current years sale.

Dream Travel produces car seats for children from newborn to 2 years old. Dream Travel​'s only problem with its car seats was stitching in the straps. The problem can usually be detected and repaired during an internal inspection.

Inspection costs$5.00 per car​ seat, and the repairs cost $ 1.00 per car seat. All 250,000 car seats were inspected last​ year, and 8% were found to have problems with the stitching. Another 4​% of the 250,000 car seats had problems with the​ stitching, but the internal inspection did not discover them. Defective units that were sold and shipped to customers are shipped back to Dream Travel and repaired. Shipping costs are $15.00 per car​ seat, and repair costs are $1.00 per car seat. Negative publicity will result in a loss of future contribution margin of $ 150 for each external failure.

Requirement 1. Identify total costs of quality by category​ (appraisal, internal​ failure, and external​ failure.)

Requirement 2.

Dream Travel is concerned with the high​ up-front cost of inspecting all 250,000 units. It is considering an alternative internal inspection plan that will cost only

$ 2.00 per car seat inspected. During the internal​ inspection, the alternative technique will detect only 4.0% of the 250,000 car seats that have stitching problems. The other 8.0%

will be detected after the car seats are sold and shipped. What are the total costs of quality for the alternative​ technique?

Requirement 3. What factors other than cost should Dream Travel Dream Travel consider before changing inspection​ techniques?

A.There could easily be serious reputation effects if the percentage of external failures increases significantly. This rise in external failures may lead to costs greater than

$ 150 per failure due to lost sales.

B. Higher external failure rates may increase the probability of lawsuits.  

C. Both of the above.

D.Neither of the​ above, cost is the only factor

Dream TravelDream Travel

should consider before changing inspection techniques.

P17.1A Combat Fire, Inc. manufactures steel cylinders and nozzles for two models of fire extinguishers: (1) a home fire extinguisher and (2) a commercial fire extinguisher. The home model is a high-volume (54,000 units), half-gallon cylinder that holds 2 1/2 pounds of multi-purpose dry chemical at 480 PSI. The commercial model is a low-volume (10,200 units), two-gallon cylinder that holds 10 pounds of multi-purpose dry chemical at 390 PSI. Both products require 1.5 hours of direct labor for completion. Therefore, total annual direct labor hours are 96,300 or [1.5 hours × (54,000 + 10,200)]. Estimated annual manufacturing overhead is $1,584,280. Thus, the predetermined overhead rate is $16.45 or ($1,584,280 ÷ 96,300) per direct labor hour. The direct materials cost per unit is $18.50 for the home model and $26.50 for the commercial model. The direct labor cost is $19 per unit for both the home and the commercial models.

Assign overhead using traditional costing and ABC; compute unit costs; classify activities as value- or non-value-added.

The company's managers identified six activity cost pools and related cost drivers and accumulated overhead by cost pool as follows.

Instructions

a. Under traditional product costing, compute the total unit cost of each product. Prepare a simple comparative schedule of the individual costs by product (similar to Illustration 17.3).

a. Unit cost—H.M. $62.18

b. Under ABC, prepare a schedule showing the computations of the activity-based overhead rates (per cost driver).

c. Prepare a schedule assigning each activity's overhead cost pool to each product based on the use of cost drivers. (Include a computation of overhead cost per unit, rounding to the nearest cent.)

c. Cost assigned—H.M. $1,086,500

d. Compute the total cost per unit for each product under ABC.

d. Cost/unit—H.M. $57.62

e. Classify each of the activities as a value-added activity or a non-value-added activity.

f. Comment on (1) the comparative overhead cost per unit for the two products under ABC, and (2) the comparative total costs per unit under traditional costing and ABC.

What are cost drivers? How do cost drivers relate to cost pools? What are some cost pools? Name two or three different cost drivers for each of these cost pools.

What are value-added processes? How do you determine if a process adds value? How does identifying value-added processes help a company run more efficiently and effectively?
