QuestionFor problems 1 to 4, state the most likely hypothesis and compute both a Pearson correlation coefficient and a Spearman correlation coefficient. For problems 1 and 2, perform the computations for all problems both by hand and using SPSS. For problems 3 and 4, use SPSS only. In each case, consider which test, Pearson or Spearman, is the more appropriate choice.
1. An HMO administrator wants to examine the relationship of self-rated health to the number of physician visits made in 1 year. The self-rated health is rated on a scale of 1 to 5 , where 1=1= poor health and 5=5= excellent health; the number of physician visits made in the past year is shown in the table below:

Patient ID Self-Rated Health No. of Physician Visits in the Past Year \begin{tabular}{lll} \hline & the Past Year \\ \hline 1 & 5 & 2 \\ \hline 3 & 4 & 1 \\ \hline 4 & 4 & 2 \\ \hline 5 & 5 & 3 \\ \hline 6 & 4 & 3 \\ \hline 7 & 3 & 4 \\ \hline 8 & 3 & 4 \\ \hline 9 & 4 & 4 \\ \hline 10 & 2 & 5 \\ \hline 11 & 2 & 5 \\ \hline 12 & 3 & 5 \\ \hline \end{tabular}
