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 r, = 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 decimal places.) lower limit upper limit What is the value of the sample test statistic? (Round your answer to three decimal places.)
