What is the appropriate statistical analysis to use: t-test for
two independent samples, t-test for dependent samples, ANOVA, or
chi-square test of independence? Please identify and explain why it
is appropriate.

why
(a) A study was conducted to see whether monetary incentives to
use less water during times of drought had an effect on water
usage. Sixty single family homeowners were randomly assigned to one

what is the independent variable. what is the dependent variable,
and what hypothesis test is it.Imagine that you are interested to see if there is a relationship between gender, people's religion and what they consider the ideal family size to be. You would likely do this by recruiting individuals from different religious groups and asking them to report what they consider the ideal amount of children in a family. Let us further say that you ended up recruiting (via random...

In the following table, The independent variable
is_______________ , and the dependent variable is_____________ What
is the null and the alternative hypotheses? Running a
chi-square analysis, you obtain a chi-square value of 22.9 with a
significance level of <0.000, which hypothesis (null or
alternative) should you, therefore, choose as
correct? Can you estimate a directionalmeasure of
association between these two variables? Why or why
not?
