If you are lost in the woods and do not have clear directional markers, will you tend to walk in a circle? To study this question, some students recruited 30 volunteers to attempt to walk the length of a football field while blindfolded. Each volunteer began at the middle of one goal line and was asked to walk to the opposite goal line, a distance of 100 yards. None of them made it. Display 9.8 shows the number of yards they walked before they crossed a sideline.
a. Are the conditions met for finding a confidence interval estimate of the mean distance walked before crossing a sideline? Explain any reservations you have.
b. Regardless of your answer to part a, construct a 99% confidence interval for the mean distance walked before crossing a sideline.
c. Interpret your interval in part b.
