The article “Opioid Use and Storage Patterns by Patients after Hospital Discharge following Surgery” (PLoS ONE 2016) reported a study of 30 women who just had Caesarian sections. The women were classified into two groups: 14 with a high need for pain medicine post-surgery and 16 with a low need. The total oral morphine equivalent prescribed at discharge was determined for each woman, and the resulting Wilcoxon rank-sum test statistic was W = 249.5. (The .5 comes from ties in the data, but that won’t affect the P-value much.) Test the hypotheses H₀: µ₁ = µ₂ versus H_a:µ₁ ≠ µ₂ at the .05 significance level. Does it appear that physicians prescribe opioids in proportion to patients’ pain-control needs?
