are from a random sample of 1010 U. S. adults surveyed in the 2002 Sleep in America Poll. Of
these, 995 responded to the question abfut snoring, indicating whether or not they had snored at
least a few nights a week in the past year. In the younger age group, 48 snored and 136 did not. In
the older group, 318 snored and 493 did not. Construct a 96% confidence interval to estimate the
difference in the snoring rates of the two age groups. You may want to do your work on paper
