Are creаtivity аnd prоblem sоlving linked tо аdequate sleep? In a research study, two hundred volunteers were randomly assigned into two equal-sized groups. Each volunteer took a test that involved transforming strings of eight digits into a new string that fit a set of given rules, as well as a third, hidden rule. Prior to taking the test, one group received eight hours of sleep, while the other group stayed awake all night. The researchers monitored the volunteers to determine whether they figured out the hidden third rule. Of the volunteers who slept, 78 discovered the third rule and of the volunteers who stayed awake all night, 30 discovered the third rule. If one were to test to determine if the sleep group discovered the third rule significantly more than the awake group, which parameter would you conduct inference on?
