2. Suppose, for a random sample of 15 firms that revalued their fixed assets, the mean ratio of debt to tangible assets was 0.517 and the sample standard deviation was 0.148. For an independent random sample of 18 firms that did not revalue their fixed assets, the mean ratio of debt to tangible assets was 0.489 and the sample standard deviation was 0.159. Assuming a normal distribution, do not assume equal variances. Find a 99% confidence interval for the difference between the two population means.
