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 sum of all frequencies.
$$112 + 310+504 + 1133+2614=4673$$

Step2: Calculate probability for 'Rarely'

Use the formula \(P=\frac{\text{Frequency}}{\text{Total Frequency}}\).
For 'Rarely', frequency is \(310\).
\(P=\frac{310}{4673}\approx0.066\)

Answer:

\(0.066\)
