"Durable press" cotton fabrics are treated to improve their
recovery from wrinkles after washing "Wrinkle recovery angle"
measures how well a fabric recovers from wrinkles. Higher is
better. Here are data on the wrinkle recovery angle (in degrees)
for the some fabric specimens.

| 104 | 199 |
| 142 | 149 |

A consumer group suspects that there is a difference in recovery
from wrinkles after washing. Specifically, they want to test the
claim that there is a difference in recovery between using
Permafresh and Hilite. To investigate this, they identified the
mean recovery from wrinkles after washing by measuring the wrinkle
recovery angle in degrees for a sample of fabrics using Permafresh,
and a sample of fabrics using Hylite.
At the 5% level of significance, is there enough evidence to
conclude that there is a difference in wrinkle recovery angle
between Permafresh and Hylite?
It is often reasonable to conclude that measurements are normal in
distribution. So it is reasonable to assume the population of
wrinkle recovery angle is normal for both Permafresh and Hylite.
Also assume that the data represents a SRS (simple random sample)
of fabrics using Permafresh and Hylite.
1) Why is this a two sample independent means test? and
Step 1: State the Claims which means to State the
null and alternative hypotheses. Use correct math type. You may
want to consider looking back at the symbols assignment from the
beginning of class.

"Durable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "Wrinkle recovery angle" measures how well a fabric recovers from wrinkles. Higher is better. Here are data on the wrinkle recovery angle (in degrees) for a random sample of fabric specimens. Assume the populations are approximately normally distributed with unequal variances. A manufacturer believes that the mean wrinkle recovery angle for Hylite is better. A random sample of 25 Hylite (group 1) and 20 Permafresh (group 2) were measured. Test the claim using a 10% level of significance.

The Garriga printing press uses a job order cost system to record business costs. Each order of a customer is treated as a separate job.
Indirect costs are allocated based on the work hours required by the client's order. If indirect costs are over-allocated or under-allocated (overapplied or underapplied), the difference is taken against the cost of goods sold because it is usually not significant.
The data for the current year is listed below.
Estimated indirect or general costs for 2019: $ 860,000
Actual indirect costs incurred in 2019: $ 879,000
Total estimated hours of work at the beginning of 2019: 50,000
Total actual work hours incurred during 2019: 52,000
Required (use points to indicate decimal points).
1. Calculate the default indirect cost rate (use points to indicate decimal points).
$
per hour
2. Calculate the indirect costs assigned (applied) (use points to indicate decimal points and commas to separate thousands).
$
3. Indicate whether indirect costs were under-allocated or over-allocated. (Answer by typing SUB or ENVELOPE, in capital letters).
4. Indicate how much indirect costs were under-allocated or
over-allocated. . (use points to indicate decimal points).

Quik Press Inc. offers one day dry cleaning. at the beginning of 2015, th company purchased a mechanized pressing machine. the owner of the company, Jill Jabowski, recently retured from an industry equipment exhibition where you saw a computerized pressing machine demonstrated. she was impressed with the machines speed, efficiency, and quality of output. upon retuning from the exhibition, she asked her purchasing agent to cleect price and operating cost data on the ew pressing machine. in addition, she asked the company's accountant to provide her with cost data on the company's pressing machine. this information is presented below:
| old pressing machine | new pressing machine | |
| purchase price | 120,000 | 150,000 |
| estimated salvage value | 0 | 0 |
| estimated useful life | 6 years | 5 years |

annual revenues are 200,00, and selling and administrative expenses are 24,000, regardless of which pressing machine is used. if it replaces the old machine now, at the beginning of 2016, Quik Press will be able to sell it for 10,000
a) determine any gain or loss if the old pressing machine is replaced
b) prepare a five year summarized income statement for each of the following assumptions:
1) the old machine is kept
2) the old machine is replaced
c) using incremental analysis, determine whther the company should replace the old pressing machine
d) The purpose of this memo is to explain to Jill why the $90,000 loss on sale is NOT relevant. In other words, explain to her why book value (historical cost – accumulated depreciation) is not relevant.

French Press Coffee Inc. (HFC) processes and distributes a variety of coffees. HFC buys coffee beans from around the world and roasts, blends, and packages them for resale. HFC sells one-pound bags of coffee throughout a series of gourmet shops. the company has low direct labor costs but very high factory overhead.
Data for the 2018 budget includes factory overhead of $2,393,500, which is currently being allocated based on direct labor cost. Budgeted direct labor is $100000.
The budgeted direct costs for a one pound bag of the two most popular coffee blends are as follows:
| Presque Isle Blend | Mentor Headlands blend | |
|
Direct material |
$4.25 | $3.50 |
| Direct labor cost | $0.95 | $0.75 |
The controller believed the current costing system generates misleading information. She has developed the following details:
| Activity | Cost Driver |
Budgeted Cost |
| Purchasing | #Purchase Orders | $474000 |
| Material Handling | #Setups | $638000 |
| Quality Control | #batches | $67500 |
| Roasting | Roasting Hours | $920000 |
| Blending | Blending Hours | $190000 |
| Packaging | Packaging Hours | $103000 |
Total Budgeted cost- $2,392,500
Additional information:
| Presque Isle Blend | Mentor Headlands Blend | |
| Sales in units | $100000 pounds | 5000 pounds |
|
Selling price per unit |
$30 | $24 |

0.50 hour per 250 pounds |
| packaging time | 0.20 hour per 1000 pounds | 0.20 hour per 1000 pound |
Required: 1. Assuming manufacturing overhead is allocated based on direct labor costs, calculate the cost per unit of Presque isle blend and mentor headlands blend.
2. Assuming the company uses Activity based costing, calculate the cost per unit of Presque Isle Blend and Mentor Headlands Blend.
