The two-way table below describes the practice habits of members of the school band and choir. which statement best describes the relationship between the two variables? there is an association because the relative frequencies by row are different. there is an association because the relative frequencies by row are similar. there is no association because the relative frequencies by row are different. there is no association because the relative frequencies by row are similar.

There is no association because the relative frequencies by row are similar.

Step-by-step explanation:

There are a total of 38+26 = 64 band students.

There are a total of 18+12 = 30 choir students.

38 out of the 64 band students practice less than 30 minutes per day; this is a relative frequency of 38/64 = 0.59 = 59%.

26 out of the 64 band students practice at least 30 minutes or more per day; this is a relative frequency of 26/64 = 0.41 = 41%.

18 out of the 30 choir students practice less than 30 minutes per day; this is a relative frequency of 18/30 = 60%.

12 out of the 30 choir students practice 30 minutes or more per day; this is a relative frequency of 12/30 = 40%.

These frequencies are nearly identical.  This means there is no difference between band students and choir students; thus there is no association between type of musician and amount of time spent practicing.

Step-by-step explanation:

Just use vectors to calculate the change in the x and y axis during each movement and then apply the Pythagoras Theorem.
