Answer:
•A c-chart is the appropriate control chart
• c' = 8.5
• Control limits, CL = 8.5
Lower control limits, LCL = 0
Upper control limits, UCL = 17.25
Step-by-step explanation:
A c chart is a quality control chart used for the number of flaws per unit.
Given:
Past inspection data:
Number of units= 100
Total flaws = 850
We now have:
c' = 850/100
= 8.5
Where CL = c' = 8.5
For control limits, we have:
CL = c'
UCL = c' + 3√c'
LCL = c' - 3√c'
The CL stands for the normal control limit, while the UCL and LCL are the upper and lower control limits respectively
Calculating the various control limits we have:
CL = c'
CL = 8.5
UCL = 8.5 + 3√8.5
= 17.25
LCL = 8.5 - 3√8.5
= -0.25
A negative LCL tend to be 0. Therefore,
LCL = 0
Answer:
11
Step-by-step explanation:
Probability of Max making a shot is 45/60=¾
Here, probability, p=¾ or 0.75
The trials n=15
E=np where E is expectation
Now, when the shots out of 15 trials will be given by np=15*¾=11.25 shots
Rounded off to the nearest interger, this is approximately 11 shots.
Therefore, the possible number of shots in 15 trials for Max is equivalent to 11
