The table at the left shows a sample of the waiting times (in days) for a heart transplant for two age groups. At a = 0.05, can you conclude that the variances of the waiting times differ between the two age groups?

(a) Identify the claim and state H₀ and H_a, 

(b) Find the critical value and identify the rejection region, 

(c) Find the test statistic F, 

(d) Decide whether to reject or fail to reject the null hypothesis, and 

(e) Interpret the decision in the context of the original claim. Assume the samples are random and independent, and the populations are normally distributed.
