**Survey Analysis of Bus Stop Waiting Times**To study the perceptions of waiting time, a researcher conducted a survey of 100 prospective passengers at bus stops. Their answers revealed a mean waiting time of 5.2 minutes with a standard deviation of 1.2. The task is to construct a 90% confidence interval for the true mean waiting time.
