Hi! I need help with computing the phi correlation coefficient in problem 11 as well as completing the table for problem 21. Once I know this data I will be able to reject or retain the null hypothesis.

11. + -/2 points PriviteraStats3 15.E.031. My Notes A therapist measures the relationship between a patient's expectations that therapy will be successful and the actual success of the therapy. The following table shows the results of this hypothetical study using a sample of 50 clients. Therapy Successful Yes No Totals Client Yes 22 8 30 expects No 4 16 20 success Totals 26 24 (a) Compute the phi correlation coefficient. (Round your answer to three decimal places.) (b) Using a two-tailed test at a 0.05 level of significance, state the decision to retain or reject the null hypothesis. Hint: You must first convert r to x2. O Retain the null hypothesis. O Reject the null hypothesis. You may need to use the appropriate table in Appendix C to answer this question. Additional Materials eBook
