A local mattress manufacturer wants to know if its manufacturing process is in or out of control and has hired you, a statistics

balandron [24]

Answer:

a. 95.4

b. UCL = 96.07

LCL = 94.73

c. Process is in control

Step-by-step explanation:

a. The computation of estimate mean is shown below:-

$Estimate\ mean = \frac{\Sigma X}{N} \\\\ = \frac{1908.000}{20}$

= 95.4

b. The computation of Upper Control Limit (UCL) and the Lower Control Limit (LCL) for the manufacturing process is shown below:-

$UCL = Mean + \frac{3\times \sigma }{\sqrt{Sample\ size} }$

$UCL = 95.4 + \frac{3\times (0.5)}{\sqrt{0.5} }$

= 95.4 + 0.67082

= 96.07

$UCL = Mean - \frac{3\times \sigma }{\sqrt{Sample\ size} }$

$UCL = 95.4 - \frac{3\times (0.5)}{\sqrt{0.5} }$

= 95.4 - 0.67082

= 94.73

c. The explanation is shown below:-

From the above calculation we can see that the sample lies between LCL AND UCL that is (94.73 ,96.07) ,

The Process is in control

The value of x is and the value of y is

TEA [102]

Answer:

x = 60, y = 50

Step-by-step explanation:

60 + 50 = 110 + 70 = 180.

50 + 70 = 120 + 6 = 180.

Therefore 50 + 70 + x = 60

Therefore 70 + 60 + y = 50
