Select one:

a. A tool for comparing population parameters inferred from samples

b. Dissecting the data

c. Help in solving problems

d. Breaking up the problem

Which hypothesis test is similar to the 1 sample t-test but is used when the data set is non-normal?

Select one:

a. 1- sample sign

b. Kruskal-Wallis

c. Friedman

d. Mann-Whitney

Which statements is correct about the Capability Analysis shown?

Select one:

a. From this study we can predict that this process will produce less than 100 parts per million that are outside of the specification limits

b. The process has a problem with centering.

c. The parts have a mean average diameter between 4 mm and 4.9 mm

d. The process needs significant improvements to be in control

Answer 1

Dear your satisfaction is more important, I provided answers with detailed explanation. If you are satisfied with my explanations please THUMBS UP.. Thanks inadvance for your support dear....

Last question (Question 3) The data is not provided but don't worry dear I will figure out the concept and choose best possible answer among the option by assuming some conditions.

1) a. A tool for comparing population parameters inferred from samples

Reason : In Parametric Hypothesis testing , we are testing the hypothesized Parameter and makes an Inference about them by utilizing sample observations

2) a. One sample sign

Reason : One Sample Wilcoxon signed rank test is a non parametric test which is an alternative to one sample t test when we can't hold normality assumption in small sample testing problems.

3) a. From this study we can predict that this process will produce less than 100 parts per million that are outside of the specification limits

Reason : From the given option the odd one is option a. Because option a seems to be different from all others. Option A seems to be an option saying about the process is under control and all others indicating the process is out of control but can't precisely say that at option c. More over I assumed the following :
