7.86 Revisiting dietary composition. In Exercise 7.71
(page 457), the total amount of fats was analyzed
using the two-sample t procedures that do not assume
equal standard deviations. Compare the means using a
significance test and find the 95% confidence interval
for the difference using the pooled methods. How do the
results compare with those you obtained in Exercise 7.71?
