Suppose the Goodyear Tire Company developed two new brands of tires and would like to compare the variability of the tire life of the two. Both brands were driven under normal conditions, and random samples of the tires were collected. The following table shows the sample sizes and the standard deviations, in miles, calculated for each sample:

a. Using α = 0.10, determine if there is a difference in the variability of the two tire brands.

b. Verify your results using PH_Stat.

c. Interpret the p value obtained from the software.
