Using Probability to Identify Unlikely Events. In Exercises 29–36, consider an event to be “unlikely” if its probability is less than or equal to 0.05. (This is equivalent to the same criterion commonly used in inferential statistics , but the value of 0.05 is not absolutely rigid, and other values such as 0.01 are sometimes used instead.) 32. All Travel Fatalities One measure of air travel safety is this: There are 117 fatalities per billion passenger flights. Express that measure as a probability. Is it unlikely for an air passenger to be a fatality? How does air travel compare to the car fatality rate of 40 fatalities per billion trips? Is this comparison fair?

Solution Summary: The author explains that the probability of fatality due to passenger flights is 0.000000117. The comparison is not fair because the distance for the trips of car and flight is different.

Statistics that allow for inferences or estimates about the population. Inferential statistics enable analysts come to conclusions about the population based on sample data. Inferential statistics cover the basics of inferential statistics, all kinds of hypotheses tests and their confidence intervals, design of experiments, and statistical power and errors. It also includes point estimation techniques, limit theorems, sampling distributions, approximations, and bounds. Correlation, regression, and association are also covered under inferential statistics to infer relationships between variables.
