This is the graph that goes with the problem

1. My local dollar store makes a 60-watt light bulb that lasts 300 hours on average. The following graph shows the probability distribution of lightbulb lifetimes, where the mean is 300. 25% 20 % 15% 10% 5% 0 0 100 200 300 400 500 600 700 800 900 1,000 Lightbulb lifetime (hrs)
