Problem 6

Determine whether the probability experiment represents a binomial experiment. If not, explain why.

(a) An urn contains 20 colored golf balls: 8 white, 6 red, 4 blue, and 2 yellow. A child is allowed to draw balls until he gets a yellow one. The number of draws required is recorded.

(b) According to the Uniform Crime Report, 2013, 16% of property crimes committed in the United States were cleared by arrest or exceptional means. Twenty-five property crimes from 2013 are randomly selected and the number that was cleared is recorded.

Step-by-Step Solution:

Step 1 of 5) Determine whether the probability experiment represents a binomial experiment. If not, explain why. (a) An urn contains 20 colored golf balls: 8 white, 6 red, 4 blue, and 2 yellow. A child is allowed to draw balls until he gets a yellow one. The number of draws required is recorded. (b) According to the Uniform Crime Report, 2013, 16% of property crimes committed in the United States were cleared by arrest or exceptional means. Twenty-five property crimes from 2013 are randomly selected and the number that was cleared is recorded. P-Value Approach Using Technology Step 3 (continued) We will use a TI-84 Plus C graphing calculator to obtain the P-value. The steps for testing hypotheses comparing two population standard deviations using the TI-83/84 Plus graphing calculators, Minitab, Excel, and StatCrunch are given in the Technology Step-by-Step on page 565. Figure 23 shows the result obtained from the TI-84 Plus C using the DRAW option. The P-value is 0.9666.
