In 2011, the U.S. Center for control and Prevention (CDC) conducted a survey to track a wide variety of risky behavior by American youth. The following table summarizes the responses of 12th grade males and females and their helmet wearing habitats.Which of the following statements are true? Select all that apply.a. 1,067/1825 is a joint relative frequency.b. 93/1160 is a conditional relative frequency .c. 93/1160 is a marginal relative frequencyd. 1160/2027 is a joint relative frequency.e. 1825/2027 is a conditional relative frequency.f.867/2027 is a marginal relative frequency.g.1067/2027 is a joint relative frequency.
Accepted Solution
A:
B) 93/1160 is a conditional relative frequency; it gives the probability of one event on the condition another is true F) 867/2027 is a marginal relative frequency; it gives the probability of one margin of the table; G) 1067/2027 is a joint relative frequency; it gives the probability of the joining of two conditions
