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 number of responses

Total frequency \( N=112 + 310+594 + 1133+2614\)
\(N=4763\)

Step2: Calculate probability for "Never"

Probability \(P(\text{Never})=\frac{\text{Frequency of Never}}{\text{Total frequency}}\)
\(P(\text{Never})=\frac{112}{4763}\approx0.023\)

Answer:

\(0.023\)
