There is not relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster.
Answer: Option A.
<u>Explanation:</u>
A scatterplot is a type of data display that shows the relationship between two variables. It makes use of the Cartesian coordinates to plot the values of the two variables for a set of data. This is used to show how much is one variable is affected by the other variable.
Since in the scatterplot which is being talked about in this question, it is scattered and is not clustered, this shows that there is no relationship between the size of the school and the number of the students who play instruments in the school.
20 is the size of a random sample of 720 marbles.
Notice that 720=20*36
If there are 2 yellow marbles in the sample of 20 marbles, then we can expect:
2*36=72 yellow marbles in the box of 720 marbles
So, B) 72 is the correct answer
