The first 10 people who arrived (on time) at a church service filled out a questionnaire on attitudes toward religion. The last 10 people to arrive (late) for the service were spotted, and they filled out the same questionnaire. High scores indicate more positive attitudes toward religion. Here is the descriptive data: On Time Xbar1=8.00 s-hat1=2.789 LL Late Place a 95% confidence interval around the difference between the means. UL Xbar2 11.00 s-hat2=2.357
