Question

(3.02) Examining the location of accidents on a level, 5-mile bike path shows that they occur uniformly along the length of the path. Figure 3.4 displays the density curve that describes the distribution of accidents. Height-1/5-- 0 Distance along bike path (miles) eBook Step 1: Explain why this curve satisfies the two requirements for a density curve Because it is symmetrical with respect to the vertical line at x-1.5 and the area beneath the curve does not extend 1 Because it is on or above the horizontal axis and the area beneath the curve is 1 Because it is a smooth curve on or above the horizontal axis Because it is on the nonnegative part of the x-axis and the area beneath the curve is 1. Step 2: The proportion of accidents that occur in the first 2 miles of the path is the area under the density curve between 0 miles and 2 miles What is this area? 1/10 2/3 1/6 2/5

Answer 1

Step 1) because it is on or above the horizontal axis and area beneath the curve is 1.
