Explanation:

Step1: Calculate prevalence for mountain bikers

Prevalence for mountain bikers = $\frac{19}{70}$

Step2: Calculate prevalence for non - mountain bikers

Prevalence for non - mountain bikers = $\frac{5}{53}$

Step3: Calculate prevalence ratio

Prevalence ratio = $\frac{\frac{19}{70}}{\frac{5}{53}}=\frac{19\times53}{70\times5}=\frac{1007}{350}\approx 2.88$

$2.88$
