1. Amaron.con is testing a new robot. Data collected from a test run showed an average cycle time of 4 minutes per job. The maximum cycle time, to be exceeded by only 3.4 jobs out of every one million jobs performed, is set to 7 minutes. What is the expected standard deviation?

1. 1 minute

2. Five thousand units of product were examined to detect possible undesirable characteristics. A total of 80 defects were found. What is the approximate process sigma?

The probability of event A is 50%. The probability of event B is 10%. What is the probability of

either event occurring?

1. 60%
2. 5%
3. 55%
4. 40%

3. What is the reliability of the three components connected in series shown below?

at least 0.85

1. 0.799425
2. 0.95000
3. 0.91333

4. It takes 4 minutes for a job to be completed on an assembly line. The throughput rate of the

bottleneck station is 1 job every two minutes. Assuming no variability, what would need to be the

maximum number of jobs in the line before jobs have start waiting?

5. If arrivals into a station increase in variability, how should the station's utilization be changed to process adequately?

6. Which availability level results in about 5 minutes of downtime per year?
