Question: When a process appears to be functioning properly when, if fact, it is out of control, the type of error and injured party is identified as:
Answer: Type II error, consumer's risk
Snippets: Probability that inaccurately
accepting the lot which is absolutely unacceptable and false is
called Type II or
Error and the risk of making it is called consumer risk.
QUESTION 5 When a process appears to be functioning properly when, if fact, it is out...
The causes of variation in statistical process control are: natural causes and assignable causes producer's causes and consumer's causes cycles, trends, seasonality, and random variations Type I and Type II errors None of them
Question 2 1 pts Concluding a process is out of control when it is actually in control is known as a Type Il error. O True O False Question 3 1 pts In the weighted moving average forecasting model the sum of weights must be less than 1. True False Question 4 1 pts In order for a process to be capable, it should have a capability index of at least 2.5. True O False Question 5 1 pts The...
You may need to use the appropriate appendix table or technology to answer this question KALI, Inc., manufactures home appliances that are marketed under a variety of trade names. However, KALI does not manufacture every component used in its products. Several components are purchased directly from suppliers. For example, one of the components that KALI purchases for use in home air conditioners is an overload protector, a device that turns off the compressor if it overheats. The compressor can be...
2 2. A bakery is interested in understanding more about the temperature of their ovens. The process calls for an average temperature of 375 degrees Fahrenheit. History has shown the process to have a standard deviation of 9 degrees Fahrenheit. They take 7 measurements during each oven run. They recorded the average of the temperature measurements for each oven run in the table below. i. Construct a 3-Sigma control chart for this process. Sample Average Temperature 1 382 379 3...
1- KALI, Inc., manufactures home appliances that are marketed under a variety of trade names. However, KALI does not manufacture every component used in its products. Several components are purchased directly from suppliers. For example, one of the components that KALI purchases for use in home air conditioners is an overload protector, a device that turns off the compressor if it overheats. The compressor can be seriously damaged if the overload protector does not function properly, and therefore KALI is...
1 of 2 (Question 1 of 2) If we fail to reject Ho when in fact He is true, this is a _ error. A Type 1 B Type II C None of the above 2 of 2 (Question 2 of 2) The mean fineness, u, of yarn is expected to be greater than the standard, value of 5 units. To test this claim, the factory graded 16 specimens of the yarn and found the sample average, X, to be...
A control chart is used for monitoring a process meanl (X) that is normally distributed with a mean of μ and a standard deviation of σχ , and the sample size is n-5. А 3-sigma limit (μ ±30% ) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is out of...
6.1.6. A process for making steel pipe is under control if the diameter of the pipe has mean 3.0 in. with standard deviation of no more than 0.0250 in. To check whether the process is under control, a random sample of size n 30 is taken each day and the null hypothesis 3.0 is rejected if X is less than 2.9960 or greater than 3.0040. Find (a) the probability of type I error; (b) the probability of type II error...
A control chart is used for monitoring a process mean ( 7 ) that is normally distributed with a mean of u and a standard deviation of o, and the sample size is n = 5. A 3-sigma limit (u +30z) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is...
