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.

Explanation:

Step1: Calculate total frequency

First, find the total number of responses.

$$
LATEXBLOCK0
$$

Step2: Calculate probability for "Most of the time"

The probability \(P\) of an event is given by \(P=\frac{\text{Frequency of event}}{\text{Total frequency}}\).
For "Most of the time" with frequency \(1381\), the probability is \(\frac{1381}{4771}\approx0.290\)

Answer:

\(0.290\)
