Chapter 5: Q 93. (page 331)

Late shows Some TV shows begin after their scheduled times when earlier programs run late. According to a network鈥檚 records, about 3% of its shows start late. To find the probability that three consecutive shows on this network start on time, can we multiply (0.97)(0.97)(0.97)? Why or why not?

Short Answer

Expert verified

No.

Step by step solution

01

Step 1. Given Information

When previous programmes run late, certain TV programmes start later than scheduled.

02

Step 2. Concept used

Multiplication rule:PA鈭�B=PA脳PB

03

Step 3. Explanation

No, because the likelihood of consecutive shows beginning late is not independent for each show (if the first show starts late, the probability of the next show starting late is increased), and so the general multiplication formula for independent events cannot be used.

Urban voters The voters in a large city are 40%white, 40%black, and 20%Hispanic. (Hispanics may be of any race in official statistics, but here we are speaking of political blocks.) A mayoral candidate anticipates attracting 30%of the white vote, 90%of the black vote, and 50%of the Hispanic vote. Draw a tree diagram to represent this situation. What percent of the overall vote does the candidate expect to get? Use the four-step process to guide your work.

Color-blind men About7%of men in the United States have some form of red-green color blindness. Suppose we randomly select one U.S. adult male at a time until we find one who is red-green color-blind. How many men would we expect to choose, on average? Design and carry out a simulation to answer this question. Follow the four-step process.

Taking the train According to New Jersey Transit, the 8:00 a.m. weekday train from Princeton to New York City has a 90% chance of arriving on time. To test this claim, an auditor chooses 6 weekdays at random during a month to ride this train. The train arrives late on 2 of those days. Does the auditor have convincing evidence that the company鈥檚 claim isn鈥檛 true? Design and carry out a simulation to answer this question. Follow the four-step process.
