In 2010 the GSS asked whether a subject was willing to accept cuts in the standard of living to help the environment (GRNSOL), with categories (vw = very willing, fw = fairly willing, nwu = neither willing nor unwilling, nvw = not very willing, nw = not at all willing). When this was cross-tabulated with whether the respondent is currently in school or has retired (WORKSTAT), as shown below, X²= 9.56.
a. What are the hypotheses for the test to which X² refers?
b. Report r and c and the df value on which X²is based.
c. Is the P-value less than 

(i) 0.05? 

(ii) 0.025? Explain.
d. What conclusion would you make, using a significance level of 

(i) 0.05

(ii) 0.025?

State your conclusion in the context of this study.
