Spearman correlation

Answer 1

The chi-square test provides a method for testing the association between the row and column variables in a two-way table. The null hypothesis H0 assumes that there is no association between the variables (in other words, one variable does not vary according to the other variable), while the alternative hypothesis Ha claims that some association does exist. The alternative hypothesis does not specify the type of association, so close attention to the data is required to interpret the information provided by the test.

Chi square test of association is the correct answer.

Fast runners and fast bikers are both categories of categorical variable. That means we are to check there is any association between fast runners and fast bikers or not.
