The fоllоwing bоxplot wаs creаted using dаta on the wait time (in minutes) for the Disney World ride Space Mountain at 5 PM on 50 different days. Approximately what percent wait times were longer than than 43 minutes? Based on the boxplot, Q1 is approximately 38. Approximately what percent of wait times are less than 38? Estimate from the boxplot. Use the values of Q1 and to calculate the limits for which values result in an outlier. Use the formulas:
