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
Answer
Explanation:
Step1: Calculate total frequency
Total frequency ( N=112 + 310+594 + 1133+2614=4763 )
Step2: Calculate probability for 'Never'
Probability ( P(\text{Never})=\frac{\text{Frequency of Never}}{N}=\frac{112}{4763}\approx0.023 )
Answer:
( 0.023 )
