Tom is the quality control manager for the company XYZ. XYZ recently received some complaints about its product A's quality and

the general manager Steve requested Tom to investigate it. To gain a better understanding of the production process, Tom decided to use p-chart to monitor and identify the assignable cause variations. For the next 8 working days, Tom collected 8 samples (each of the size 100 units) and found the following number of defects, 4, 6, 0, 1, 3, 5, 8, 3.
a. What is the defect rate for sample 2? Ignore the percentage sign, and round your answer to the nearest integer. For example, if your answer is 12.34%, input 12.

Your answer is .

b. What is p-bar? Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34. (Note that this is different from question a.)

Your answer is .

c. What is sigma? Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34.

Your answer is .

d. What is upper control limit UCL for this p-chart? Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34.

Your answer is .

e. What is lower control limit LCL? (If LCL is negative, input 0) Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34. If your answer is -1.234%, input 0.

Your answer is .

f. How many outlier(s) is(are) identified? Round your answer to the nearest whole number. For example, if the answer is 3.12, input 3.

Your answer is

Answer:

Answer a= Defect rate of sample 2= 6/100 =6

Answer b=

Data  % defect % defect

4      4/800            0.005

6     6/800           0.0075

0     0/800                 0

1      1/800           0.00125

3      3/800           0.00375

5      5/800           0.00625

8      8/800              0.01

3     3/800          0.00375

Sum            0.0375

p bar =0.0375

Answer c= sigma = [p bar(1-p bar) / sample size]]0.5

Sigma = (0.0375*(1-0.0375)/100)^0.5 =0.019

Answer d= UCL=p bar + 3*(Estimated standard deviation) = 0.0375+3*0.019 =0.0945

Answer e= LCL=p bar - 3*(Estimated standard deviation) =0.0375-3*0.019 =-0.0195=0

A solution was made by dissolving 800. 0 g of NaOH in 25,200 g of water. Calculate the morality, molality, and mole fraction of
maks197457 [2]

The morality, molality, and mole fraction of NaOH is mathematically given as

  1. morality= 4 ppm
  2. molality=0.7936m
  3. x1 = 0.152

What are the morality, molality, and mole fraction of NaOH?

Question Parameters:

A solution was made by dissolving 800. 0 g of NaOH in 25,200 g of water.

Generally, the equation for the Molality   is mathematically given as

molality = (mass / molar mass) x (1/ weight of solvent kg)

Therefore

M= (800 /40) x (1 /25.2)

M=0.7936m

Therefore

m= 10 x 18 / 1000

m= 0.18

Hence

x1 = 0.18 - 0.18 x1

1.18 x1 = 0.18

x1 = 0.152

Where the mole fraction is x1 = 0.152 The mass is

m= (800 / 800 + 2000) x 1000

m= 28.57 %

Hence the morality

molality = mg /L

molality= 8000 x 10^-3 / 2 L

morality= 4 ppm

In conclusion, the morality, molality, and mole fraction of NaOH are given respectively as

morality= 4 ppm

molality=0.7936m

x1 = 0.152

The following items appear on the balance sheet of a company with a one-year operating cycle. Identify the proper classification
nexus9112 [7]

Answer:

1. Notes payable (due in 13 to 24 months) - Long term Liability

This note will be owed for a period of more than 1 year. When this happens the note is said to be Long term.

2. Notes payable (due in 6 to 11 months). - Current Liability

As this note is due in a period less than a year, it is considered a current Liability.

3. Notes payable (mature in five years). - Long term Liability

This is a note that matures in a period more than a year making it a Long term Liability.

4. Current portion of long-term debt. Current Liability.

The current portion is due to be paid within the period so it is short term and hence a Current Liability.

5. Notes payable (due in 120 days). Current Liability.

Due in less than a year.

6. FUTA taxes payable. Current Liability

Taxes are generally considered a short term Liability until they are paid.

7. Accounts receivable. N (Not a Liability)

Accounts Receivable are Assets.

8. Sales taxes payable. Current Liability.

Taxes are generally considered a short term Liability until they are paid.

9. Salaries payable. Current Liability.

These salaries are owed for the period but have not been paid making them Current.

10. Wages payable. Current Liability.

Same as above. They are owed for the period but not yet paid.

forsale [732]

Answer:

The correct answer is C.

Explanation:

Giving the following information:

A machine with a cost of $65,000 has an estimated residual value of $5,000 and an estimated life of 4 years or 18,000 hours.

To calculate the depreciation expense for each year, we need to use the following formula:

Annual depreciation= 2*[(book value)/estimated life (years)]

Year1= [(65,000 - 5,000)/4]*2= $30,000

Year2= [(60,000 - 30,000)/4]*2= $15,000
