One hundred volunteers were divided into two equal-sized groups. Each volunteer took a math 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 8 hours of sleep, while the other group stayed awake all night. The sclentists monitored the volunteers to detemine whether and when they figured out the rule. Of the volunteers who slept, 38 discovered the rule of the fer Let p1 be the proportion of volunteers who figured out the third rule in the group that slept and let p2 be the proportion of volunteers who figured out the third rule in the group that stayed awake all night. The 95% confidence interval for (p1-p2) is ( OD Round to the nearest thousandth as needed.) Interpret the result. Choose the correct answer below. A. There is sufficient evidence that the proportion of those who slept who figured out the rule is greater than the corresponding proportion of those who stayed awake. B. There is insufficient evidence that the proportion of those who slept who figured out the rule is greater than the corresponding proportion of those who stayed awake
