If the probability that event A occurs is 0.51, the probability that event B occurs is 0.64 and events A and B are statistically independent then:
When comparing two vendors’ machines it is found that a sample of 1000 parts from machine A has 23 defectives and a sample of 1300 parts from machine B has 36 defectives. Do the data indicate that machine B has a higher rate of defectives?
The primary metric for a project is reduced cost for process A .A consequential metric could be:
A population of size 1,000,000 has mean 42 and standard deviation 6. Sixty random samples, each of size 15 are selected. According to the Central Limit Theorem the distribution of the sixty sample means has a mean of approximately:
An experiment has seven factors with two levels each. The experiment has eight runs. This experimental design is called:
A team wants a technique for improving consistency of assembly operations. They should use:
A team wants a technique for determining and displaying priorities based on frequency of various defect types. They should use:
A random sample is selected from a population of measurements. The mean of the sample is not equal to the mean of the population. This is due to:
An automatic gaging system is to be installed in a process. The gage will insert data values into a data base from which machine adjustments will be made automatically. A critical factor in specifying the equipment is:
