Question:

Students of the author randomly selected 217 student cars and found that they had ages with a mean of 7.89 years and a standard deviation of 3.67 years. They also randomly selected 152 faculty cars and found that they had ages with a mean of 5.99 years and a standard deviation of 3.65 years. Using a significance level of 0.05, is there sufficient evidence to support the claim that ages of student cars vary more than the ages of faculty cars? Use the results from the accompanying StatCrunch display.
