64% of all drivers use seat belts, while the remaining 36% do not use seat belts. Drivers using a seat belt have 0.2% chance to be stopped for a moving violation. In contrast, drivers that do not use a seat belt have a 0.5% chance to be stopped for a moving violation. A random driver is stopped for a moving violation, what is the probability that the driver will have a seat belt?
Homework Answers
Baye's Theorem
P(A | B) = P(A and B)/P(B)
P(driver will have a seat belt | stopped for a moving violation) = P(driver will have a seat belt and stopped for a moving violation) / P(stopped for a moving violation)
= 0.64x0.002/(0.64x0.002 + 0.36x0.005)
= 0.4156

A consumer agency wants to estimate the proportion of all drivers who wear seat belts while driving. A preliminary study of 600 people has shown that 436 of drivers wear seat belts while driving. How large should the sample size be so that the 99% confidence interval for the population proportion has a maximum error of .03?

This is the Probability and Sampling Distribution Model in Statistics Federal law under Title 49 of the United States Code, Chapter 301, Motor Vehicle Safety Standard took effect on January 1, 1968 and required all vehicles (except buses) to be fitted with seat belts in all designated seating positions. While most states have laws requiring seat belt use today, some people still do not “buckle up.” Let’s assume that 90...

Surveys have indicated that in a given region 79% of car occupants wear seat belts regardless of where they sit in the car. Wearing of seat belts in the region is random and shows no regular pattern. The surveys have shown also that in 45% of cars the driver is the sole occupant, in 25% there are two occupants, in 15% three occupants, in 10% four occupants and in 5% five occupants. a) What is the probability that a car...

A study was conducted to compare the proportion of drivers in Boston and New York who wore seat belts while driving. Data were collected, and the proportion wearing seat belts in Boston was 0.581 and the proportion wearing seat belts in New York was 0.832. Due to local laws at the time the study was conducted, it was suspected that a smaller proportion of drivers wear seat belts in Boston than New York. (a) Find the test statistic for this...

A survey of drivers in the United States found that 15% never use a cell phone while driving. Suppose that drivers arrive at random at an auto inspection station. If the inspector checks 10 drivers, what is the probability that at least one driver never uses a cell phone while driving? (Round your answer to the hundredth.) Suppose the inspector checks 1000 drivers. Use the normal approximation to the binomial distribution to find the approximate probability that at least 13%...
