Question

in a national survey college students were asked, \how often do you wear a seat - belt when riding in a car driven by someone else?\ the response frequencies appear in the table to the right. (a) construct a probability model for seat - belt use by a passenger. (b) would you consider it unusual to find a college student who never wears a seat belt when riding in a car driven by someone else? (a) complete the table below response probability never 0.024 (round to the nearest thousandth as needed.) rarely (round to the nearest thousandth as needed.)

Explanation:

Step1: Calculate total frequency

$10 + 33+57 + 111+237=448$

Step2: Calculate probability of 'Rarely'

$P(\text{Rarely})=\frac{33}{448}\approx 0.074$

Answer:

0.074
