In Yellowstone National Park, the geyser Old Faithful alternates between bursts of eruption, which typically last 1.5 to 4 minutes, and periods of dormancy, which last much longer. The table below represents the durations, in minutes, of 60 dormancy periods that occurred during a recennt year.
1. Create a frequency distribution for the data that is grouped into 6 classes. There should be a column for relative frequency.
2. Calculate the mean of the grouped data.
