TABLE 18-4
a Factory Supervisor Is Concerned That the Time

question 24

Short Answer

TABLE 18-4
A factory supervisor is concerned that the time it takes workers to complete an important production task (measured in seconds) is too erratic and adversely affects expected profits. The supervisor proceeds by randomly sampling 5 individuals per hour for a period of 10 hours. The sample mean and range for each hour are listed below.

$\begin{array} { l l l }\text { Hour }&\bar{X} &R\\ \hline 1 & 18.4 & 25 \\ 2 & 16.9 & 27 \\ 3 & 23.0 & 30 \\ 4 & 21.2 & 23 \\ 5 & 21.0 & 24 \\ 6 & 24.0 & 25 \\ 7 & 19.3 & 12 \\ 8 & 15.8 & 14 \\ 9 & 20.0 & 13 \\ 10 & 23.0 & 11 \end{array}$
She also decides that lower and upper specification limit for the critical-to-quality variable should be 10 and 30 seconds, respectively.

Definitions:

Muscle Spindle

Muscle spindles are sensory receptors within the belly of a muscle that primarily detect changes in the length of the muscle, thereby helping to regulate muscle contraction.

Action Potentials

Rapid rises and falls in the membrane potential of a cell, fundamental in the conduction of electrical impulses along nerves and muscle fibers.

Sensory Neurons

Neurons that transmit signals from sensory receptors towards the central nervous system, carrying information about external or internal conditions.

Gamma Motor Neurons

Neurons that control the contraction of intrafusal muscle fibers in muscle spindles, helping to regulate muscle tone and sensitivity of stretch reflexes.
