The Honda Ridgeline was among the highest-ranked compact pickups in J.D. Power and Associates’ annual customer-satisfaction survey. The study also found that models with high ratings have a tendency to stay on dealers’ lots a shorter period of time. As an example, the Honda Ridgeline had stayed on dealers’ lots an average of 24 days. The file titled Honda contains 50 lengths of stay on dealers’ lots for Ridgeline trucks.

b. Determine the average length of stay on dealers’ lots for the Honda Ridgeline. Does this agree with the average obtained by J.D. Power and Associates? Explain the difference.
