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 (round to the nearest thousandth as needed.)

Explanation:

Step1: Calculate total frequency

$108 + 338+574 + 1129+2271=4420$

Step2: Calculate probability of 'Never'

$P(\text{Never})=\frac{108}{4420}\approx 0.024$

Answer:

$0.024$
