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 . The standard deviation of the sample mean is . The UCL

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:

Compute the 3σ lower control limit as follows:

Thus, the UCL is 3.636 and the LCL is 2.964.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

pls mark as brainliest

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
