Question

The article "Determination of Most Representative Subdivision"t gave data on various characteristics of subdivisions that could be used in deciding whether to provide electrical power using overhead lines or underground lines. Here are the values of the variables y = number of culs-de-sac and z = number of intersections: y 1 0 1 002 011 1 210011 01111 00 0 Z 1 8 6 1 1 5 3 0 0 4 4 0 0 1 2 1 4 0 4 0 3 0 1 1 y1 1 20122110 211 01503011 0 0 z 0 1 3 2 46 6 0 1 1 8 3 3 5 0 5 2 3 10 0 03 (a) Construct a histogram for the y data. What proportion of these subdivisions had no culs-de-sac? At least one cul-de-sac? (Round your answers to three decimal places.) no çuls-de-sac at least one cul-de-sac Construct a histogram for the z data. What proportion of these subdivisions had at most five intersections? Fewer than five intersections? (Round your answers to three decimal places.) (b) at most fiver intersections fewer than five intersections

Explanation / Answer

(a)

Proportion of these subdivisions had no culs-de-sac is 17/47=0.362

Proportion of these subdivisions had at least one culs-de-sac is 30/47=0.638

(b)

Proportion of these subdivisions had at most five itersections is 42/47=0.894

Proportion of these subdivisions had fewer than five intersections is 39/47=0.830
