Question

the following segmented bar graph shows whether adults and children enjoy riding roller coasters at least once a year. how many more times likely are children to enjoy riding roller coasters at least once a year than are adults? 2.5 times more likely 2.8 times more likely 3.5 times more likely 4 times more likely

Explanation:

Step1: Estimate proportion of children who enjoy

Assume the bar for children is divided such that about 70% of the bar for children represents those who enjoy roller - coasters.

Step2: Estimate proportion of adults who enjoy

Assume the bar for adults is divided such that about 30% of the bar for adults represents those who enjoy roller - coasters.

Step3: Calculate the ratio

Let the proportion of children who enjoy be \(C = 0.7\) and the proportion of adults who enjoy be \(A=0.3\). The ratio of the proportion of children who enjoy to the proportion of adults who enjoy is \(\frac{C}{A}=\frac{0.7}{0.3}=\frac{7}{3}\approx2.3\) times.

Answer:

2.3 times more likely
