In carrying out a work sampling study in a machine shop, it was found that a particular lathe was down for 20% of the time. What would be the 95% confidence interval of this estimate if 100 observations were made?
The first algorithm for Linear Programming was given by:
Preliminary work sampling studies show that machine was idle 25% of the time based on a sample of 100 observations. The number of observations needed for a confidence level of 95% and an accuracy of ± 5% is:
Number of observations needed for 95% confidence level and ± 5% accuracy is :
If at the optimum in a linear programming problem, a dual variable corresponding to a particular primal constraint is zero, then it means that
Which one of the following correctly explains process capability?
Consider the following Linear Programming Problem (LPP):
Maximize z = 3x1 + 2x2
Subject to x1 ≤ 4
x2 ≤ 6
3x1 + x2 ≤ 18
x2 ≥ 0, x2 ≥ 0
Process capability of a machine is defined as the capability of the machine to:
Process capability of a machine is defined as the capability of the machine to hold a definite spectrum of tolerances and surface finish.
A manufacturer produces two types of products, 1 and 2, at production levels of x1 and x2 respectively. The profit is given is 2x1 + 5x2. The production constraints are:
The maximum profit which can meet the constraints is:
Rearranging the above equations and Draw the lines and get solution.
Match List-I with List-II and select the connect answer using the codes given below the lists:

Match List-I with List-II and select the correct answer using the codes given below the lists:
An operating characteristic curve (OC curve) is a plot between
OC Curve (Operating Characteristic Curve)
OC CURVE is a plot between percentage of defective and probability of acceptance.
A feasible solution to the linear programming problem should
A feasible solution to the linear programming problem should satisfy the problem constraints.
Assertion (A): Double sampling is preferred over single sampling when the quality or incoming lots is expected to be either very good or very bad.
Reason (R): With double sampling, the amount of inspection required will be lesser than that in the case of single sampling.
