How often do you go out dancing? This question was asked by a professional survey group on behalf of the National Arts Survey. A random sample of n,
= 98 single men showed that r,
= 24 went out
dancing occasionally. Another random sample of n, = 91 single women showed that
18 went out dancing occasionally. Note: For degrees of freedom d.f. not in the Student's t table, use the
closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer.
(b) Compute a 90% confidence interval for the population difference of proportions p, – p, of single men and single women who occasionally go out dancing. (Round your answers to three
