Most popular questions from this chapter

A smash or a hit?Researchers asked 150 subjects to recall the details of a car accident they watched on video. Fifty subjects were randomly assigned to be asked, “About how fast were the cars going when they smashed into each other?” For another 50 randomly assigned subjects, the words “smashed into” were replaced with “hit.” The remaining 50 subjects—the control group—were not asked to estimate speed. A week later, all subjects were asked if they saw any broken glass at the accident (there wasn’t any). The table shows each group’s response to the broken glass question.

(a) What proportion of subjects were given the control treatment?

(b) Find the distribution of responses about whether there was broken glass at the accident for the subjects in this study using relative frequencies.

(c) What percent of the subjects were given the “smashed into” treatment and said they saw broken glass at the accident?
