Question
Chapter 3, Problem 6P
(a)
Summary Introduction
Interpretation: a control chart for evaluating mean and range is to be drawn.
Concept Introduction:
A control chart is used to find out the defects in the constant
(b)
Summary Introduction
Interpretation: the value of the sample size through 16 to 25 are to be plotted on the basis of solution emerged in part a and deciding whether the process is in control.
Concept Introduction:
A control chart is used to find out the defects in the constant sample size. Control chart is generally used when it become difficult to detect the actual number of defects.
(c)
Summary Introduction
Interpretation: If the process in part b, is not in control, whether it will be included in the mean as increase in the variability or both is to be determined.
Concept Introduction:
From the above calculations it has been concluded that the means of the process is not in control.

Racks Company has developed the following standards for one of its products:
Direct materials 12 kilograms @ $14 per kg
Direct labour 3 hours @ $18 per hour
Variable overhead 3 hours @ $ 8 per hour
The following activities occurred during the month of October:
Materials purchased 10,000 kilograms at $13.60 per kg
Materials used 9,000 kilograms
Units produced 800 units
Direct labour 2,500 hours at $19.00 per hour
Actual variable overhead $22,000
The company records materials price variances at the time of purchase.
Racks Company's materials price variance would be
Racks Company's materials usage variance would be
Racks Company's labour rate variance would be
Racks Company's labour efficiency variance would be
Who would NOT be responsible for an unfavourable material usage variance caused by poor quality material?
15-19 A new president at Big State University has made student satisfaction with the enrollment and registration process one of her highest priorities. Students must see an advisor, sign up for classes, obtain a parking permit, pay tuition and fees, and buy textbooks and other supplies. During one registration period, 10 students every hour are sampled and asked about satisfaction with each of these areas. Twelve different groups of students were sampled, and the number in each group who had at least one complaint is as follows: 0, 2, 1, 0, 0, 1, 3, 0, 1, 2, 2, 0. Develop upper and lower control limits (99.7%) for the proportion of students with complaints.

- As manager of The Fitness Center, Dana is constantly try-ing new initiatives to keep her clients fit. Recent studies show that using several different cardio regimens for shortperiods of time is more effective than an extended periodof time on one type of equipment. Dana has taken some ofthe existing cardio equipment and arranged them in a lineas follows: stationary bike, treadmill, stair stepper. Clients would select this part of the gym for cardio “circuit train-ing,” spending 15 minutes at each piece of equipment for a total cardio workout time of 45 minutes.a. If the reliability of the bike is 96%, the treadmill is 95%,and the stair stepper is 92%, what is the probability thata client can complete his or her workout uninterruptedby faulty equipment?b. Dana has added a second cardio “line” for circuittraining with the same type of equipment as the firstline. This equipment, however, is older with reliabilitiesof 80% each. If only one client were using the cardiocircuit training…arrow_forwardCross-departmental teams work concurrently to get things done (those that work in short production cycles to produce product increments across time).
