Question

Jordan computed in a two-way table the relative frequencies of the weather on practice days and game days during his football season.

Weather During Football

Raining
Not Raining
Practices
23%
77%
Games
13%
87%

Which statement best describes the relationship between the two variables?
There appears to be an association because the relative frequencies by column are different.
There appears to be an association because the relative frequencies by row are different.
There does not appear to be an association because the relative frequencies by column are different.
There does not appear to be an association because the relative frequencies by row are different.

Answer 1

any ideas? as a hint, if the relative frequencies by column are the same, then there's no association (it would indicate that raining vs not raining has no effect on the game percentages)
if the relative frequencies in the columns are different, then there is an association, since that indicates that the variable raining vs not raining does cause the percentages to deviate

try to see which of these two scenarios would apply based on the data
