Sleepiness In a clinical trial of OxyContin (oxycodone) used for pain relief, 227 subjects were treated with OxyContin and 52 of them experienced sleepiness (based on data from Purdue Pharma L.P.). If OxyContin has no effect on sleepiness, the probability of getting these sample results by chance is less than 0.001 (when comparing this sample group with another group not treated with OxyContin). What do you conclude?
