A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are

in control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results.
Machine 1 Measirement 17 15 15 17
Machine 2 Measurement 16 25 18 25
Machine 3 Measurement 23 24 23 22

What are the Mean chart three-sigma upper and lower control limits?

a. 22 and 18
b. 23.16 and 16.84
c. 22.29 and 16.71
d. 23.5 and 16.5
e. 24 and 16

Answer:

b. 23.16 and 16.84

Explanation:

Mean (X-bar) = Sum of observations / No of observations

Range (R) = Highest observation - Lowest observation

<u>Machine 1 </u>

Mean (X-bar) = (17 + 15 + 15 + 17) / 4

Mean (X-bar) = 16

Range (R) = (17 - 15)

Range (R) = 2

<u>Machine 2</u>

Mean (X-bar) = (16 + 25 + 18 + 25) / 4

Mean (X-bar) = 21

Range (R) = (25 - 16)

Range (R) = 9

<u>Machine 3</u>

Mean (X-bar) = (23 + 24 + 23 + 22) / 4

Mean (X-bar) = 23  

Range (R) = (24 - 22)

Range (R) = 2

Mean of means (X-double bar) = Sum of X-bar / Number of samples = (16 + 21 + 23) / 3 = 20

Mean of ranges (R-bar) = Sum of R / Number of samples = (2 + 9 + 2) / 3  = 4.33

From table of constants for calculating the 3-sigma upper and lower control limits, For n = 4, A2 = 0.729

UCL = X-double bar + (A2 x R-bar)

UCL = 20 + (0.729 x 4.33)

UCL = 23.1566

UCL = 23.16

LCL = X-double bar - (A2 x R-bar)

LCL = 20 - (0.729 x 4.33)

LCL = 16.8434

LCL = 16.84

The value of what you owe minus what you owe is called
aliina [53]
Hey there!

I think you meant to type "value of what you <em>own</em> minus what you owe". Let me know if this assumption isn't correct, though I don't know what the value of what you owe is besides... ya know, what you owe. 

The value of what you own is called you assets. This can include anything of value that you own, particularly your pricier possessions. Think of a vintage family heirloom or a highly–priced article of clothing. Assets, though, includes the value <em>everything</em> that you own that you could possibly put a price tag on if you were certain someone would buy it. 

What you owe is called your liability. This is basically any debt that you owe anyone, whether it be your buddy who footed your lunch bill the other day when you didn't have enough cash or a student loan you used to pay for college. 

Your assets minus your liability is called your net worth. This is basically what you are worth in total. This makes sense, since any debt you owe will be taken out of the amount that you are worth or any money that you have.

Net worth will be your answer. 

Hope this helped you out! :-)
