a

Summary Introduction

Interpretation:

Circumstances in which “The probability law describing the number of periods until the process goes out of control follows the geometric distribution” will fail.

Concept Introduction:

Geometric distribution consider a sequence of Bernoulli trials, with constant probability of success p in a single trial. 

b

Summary Introduction

Interpretation:

Circumstances in which “The assumption that an out of control condition corresponds to a a shift of the mean equal to δ σ ” will fail.

Concept Introduction:

Standard deviation measures the spread of random variables or the given data from central tendency values or mean. It shows how far the deviation is from mean. A low value of standard deviation shows values are close to mean.

c

Summary Introduction

Interpretation:

Circumstance in which “ the assumption that the search cost is a fixed constant a2 ” will fail.

Concept Introduction:

Search cost is a transaction cost. It shows the amount of costs required to find a better product. If the cost gets higher, it leads to increase in transaction cost, thereby becoming a loss to consumer.

Output from a process contains 0.02 defective unit. Defective units that go undetected into final assemblies cost $25 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who can test 20 units per hour, is paid $8 per hour, including fringe benefits. Should an inspection station be established to test all units?   Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether or not the inspection operation is added. a-1. Without the inspector, what is the current hourly cost of defects?   a-2. Should an inspection station be established to test all units based on costs alone? multiple choice Yes No a-3. If the inspection operation is added, what would be the cost to inspect each unit? Note: Round your answer to 2 decimal places.   b. What would be the benefit (or loss) from establishing the inspection process? Note: Round your answer…
Suppose that you have a four-sided die that is equally weighted (i.e. equal chance of any of the four sides landing face up). The four values on the die are [12.5968, 2, -2 and -12.5968] . If we roll the die 81 times, record the average, and repeat this process a total of 100 times, what does the central limit theorem predict will be the distribution of the averages?   a) x-bar ~ N(0, 9)   b) x-bar ~ N(12.59, 1)   c) x-bar ~ N(0, 81)   d) x-bar ~ N(0, 1)

If we roll the die 81 times, record the average, and repeat this process a total of 100 times, what does the central limit theorem predict will be the shape of the distribution of the set of averages?   a) Uniform   b) Non-normal   c) No requirements, any shape   d) Bell Shaped
