Answer:

12.5%

Step-by-step explanation:

I warn you, I'm not positive I'm correct.

First I added 8+10+6 and got 24

I divided that by 3 and got 8

I divided 100 by 8 because if you cross multiply 1/8 and x/100 you would get 8x = 100

100 ÷ 8 = 12.5

So I got 12.5%

Construct a control chart for the Lard-O example using 3 sigma limits if samples of size 10 are randomly selected from the proce

densk [106]

Answer:

The UCL is 3.636 and the LCL is 2.964.

Step-by-step explanation:

The complete question is:

Construct a control chart for the Lard-O example using 3 sigma limits if samples of size 10 are randomly selected from the process. The center line is 3.3. The standard deviation of the sample mean is 0.112. The UCL = ____. The LCL = ____.

Solution:

The control chart is a graphical display used to study how a process changes over time. The data are plotted in time order.

The parts of a control chart are a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit.

These lines are formed using the historical data.

The information provided is:

Center line = m = 3.3

Standard deviation = s = 0.112

Compute the 3σ upper control limit as follows:

$\text{UCL}=m+3s$
