Question: The correlation was found between self-reported political orientation (1 = Extremely Liberal; 9 = Extremely Conservative) and support for the legalization of medical marijuana (1

The correlation was found between self-reported political orientation (1 = Extremely Liberal; 9 = Extremely Conservative) and support for the legalization of medical marijuana (1 = Strongly Against; 5 = Strongly Support). Is this correlation significantly different from 0 (no relationship) in the population?

Data: r = -.18, N = 412

a. Fully interpret the sample correlation. That is, indicate the direction, the size, and define what the correlation means in the context of these two variables.

b. State the null as well as the alternative hypothesis. Be sure to include symbols as well as words.

c. Identify the critical value and draw the rejection regions. Be sure to note the alpha level (i.e., the criterion) and degrees of freedom associated with this value.

d. Calculate the appropriate t-test to answer this question.

e. Reject or retain the null hypothesis, make a statement regarding the population correlation, and interpret the pvalue associated with the sample correlation (i.e., make a statement regarding the likelihood of the sample correlation if the null hypothesis is true)
