Explain how the Mann-Whitney U-test is similar to a t-test for
independent groups. Which other non-parametric test (that we
learned in this course) is similar to the t-test for correlated
groups?

Give an overview of the test.
State what parametric test it replaces.
Provide an example of when you would choose to use that
test.

Most people believe you shouldn’t use a Mann-Whitney test if the
data is interval/ratio, symmetric, and normal. They think a t-test
is better. Why might this be?
When can a z-test successfully be used instead of a chi-square
test (for the same data)?

a man Whitney test is used to evaluate the difference between
two treatments, with a sample of n=10 participants in each
treatment. using a two tailed test with a=.05, what value of U is
necessary to conclude that there is a significant difference
between
between treatments

1.The notion of sustainability is used differently in economics
than in the natural sciences. Explain the meaning of sustainability
in these two frameworks, and discuss the attempts that have been
made by economists to make the concept operational.

200 miles from coastlines offer the prospect of significant
improvements in the efficiency of commercial fishing
