Question 20

Assessing process proportion as opposed to evaluating a process with respect to a set target can be done using which of these?

    Correct Answer: B

    Assessing process proportion as opposed to evaluating a process with respect to a set target is done by determining whether the process proportion equals some desired value. This approach is used to test a hypothesis about a population proportion, comparing it against a specific target percentage. For example, if we need to assess whether the proportion of defect-free products in a manufacturing process meets a desired target such as 95%, we compare the sample proportion to this desired value rather than a range or interval.

Discussion
InvisibleBeingOption: B

Proportion hypothesis is always done against a population proportion target value, not the range. For example, can we prove that 40% of the population has brown eyes? 40% here is a target value that you will compare against the sample proportion. There is no statistic-test to test a population proportion range, for example 40% to 60% of the population. Intervals or ranges are only predicted with Confidence Intervals.
