You are testing the null hypothesis that there is no linear relationship between two variables, X and Y. From your sample of n = 9, you determine that r = 0.5. a. What is the value of tSTAT? b. At the = 0.05 level of significance, what are the critical values? c. Based on your answers to (a) and (b), what statistical decision should you make? a. What are the hypotheses to test? OA. Ho p=0 H p=0 OC. Ho p0 H p <0 tSTAT (Round to four decimal places as needed.) b. The lower critical value is (Round to four decimal places as needed.) The upper critical value is (Round to four decimal places as needed.) c. What statistical decision should you make? A. Since tSTAT is greater than the upper critical value, reject Ho B. Since tSTAT is between the critical values, do not reject Ho- C. Since tSTAT is between the critical values, reject Ho D. Since tSTAT is greater than the upper critical value, do not reject Ho OB. Ho p=0 H p=0 OD. Ho p0 H p>0
