3.4 What’s the statistic? A state representative wants to know
how voters in his district feel about enacting a statewide smoking
ban in all enclosed public places, including bars and restaurants.
His staff mails a questionnaire to a simple random sample of 800
voters in his district. Of the 800 questionnaires mailed, 152 were
returned. Of the 152 returned questionnaires, 101 supported the
enactment of a statewide smoking ban in all enclosed public places.
The statistic is
(a) 152/800 = 19.0%
(b) 101/800 = 12.6%
(c) 101/152 = 66.4%
(d) unable to be determined based on the information
provided.
