Question: The Texas Transportation Institute at Texas A\&M University conducted a survey to deter- mine the number of hours per year drivers waste sitting in traffic. Of 75 urban areas studied, the most jammed urban area was Los Angeles where drivers wasted an average of 90 hours per year. Other jammed urban areas included Denver, Miami, and San Francisco. Assume sample data for six drivers in each of these cities show the following number of hours wasted per year sitting in traffic.

1. Compute the sample mean hours wasted per year for each of these urban areas.
2. Using \(\alpha=.05\), test for significant differences among the population mean wasted time for these three urban areas. What is the \(p\) -value? What is your conclusion?
