Answer:
b. 0.67
Explanation:
UCL = 1 + 0.10
= 1.10 inch
LCL = 1 - 0.10
= 0.9 inch
standard deviation = 0.005 inch
mean = 1 inch
Cpk
= min[(UCL - mean)/(3*standard deviation) , (mean - LCL)/(3*standard deviation))]
= min[(1.10 - 1)/(3*0.05) , (1 - 0.9)/(3*0.05))]
= min[0.67 , 0.67]
= 0.67
Therefore, Theprocess capability index (Cpk) if the long-run process mean is 1 inch is 0.67
Answer:
750
Explanation:
The number of units in finishing department at the end of the month shall be calculated as follows:
Number of units transferred=Starting wip inventory+units received from molding department-number of units at the end of month.
Number of units at the end of month=Starting wip inventory-number of units transferred+units received from molding department
Number of units at the end of month=700-2,150+2,200
=750
Answer: The probabilities of winning a contract are
Let the Probability of C winning the contract - P(C) be 'X'
Then,
Probability of B winning the contract - P(B) will be '7X' and
Probability of A winning the contract - P(A) will be
Since the total of all the probabilities is 1,
So,
