Repeat Exercise 7.6.7, assuming that the means and standard deviations are as given in the table, but that the sample sizes are only one-tenth as large (i.e., 53 men and 42 women).
Exercise 7.6.7
As part of a large study of serum chemistry in healthy people, the following data were obtained for the serum concentration of uric acid in men and women ages 18-55 years.

Construct a 95% confidence interval for the true difference in population means. Suppose the investigators feel that the difference in population means is "clinically important" if it exceeds 0.08 mmol/1. Does the confidence interval indicate whether the difference is "clinically important"?
