Question

practice
for exercises 1-2, use the graph to describe the relationship shown.

1. height and shoe size
2. running

for exercise 3, answer the question.

1. stem connection what would you expect the association to be between the number of wolves in a state park (predators) and the number of bison (prey)?

for exercises 4-6, use the description and table to answer the questions.
the table shows the relationship between the number of missing homework assignments a student has and the number of questions they missed on a recent test.

1. what would you expect the association to be for this relationship?
2. make a scatter plot of the data.
3. does the scatter plot support your answer to exercise 6? explain.

table:

number of missing assignments	number of questions missed
3	4
6	7
9	9

scatter plot grid for exercise 5: x-axis (number of missing assignments) 0-9, y-axis (number of questions missed) 0-9

Explanation:

Exercise 1: Height and Shoe Size Relationship

Step1: Analyze the scatter plot trend

The scatter plot for "Height and Shoe Size" has points that generally go up from left to right. As height (x - axis) increases, shoe size (y - axis) also tends to increase.

Step2: Describe the association

This indicates a positive association (or positive correlation) between height and shoe size. The relationship appears to be linear (the points follow a roughly straight - line pattern) with a positive direction.

Step1: Analyze the scatter plot trend

For the "Running" scatter plot, as the distance run (x - axis) increases, the average running speed (y - axis) decreases. The points go down from left to right.

Step2: Describe the association

This shows a negative association (or negative correlation) between distance run and average running speed. The relationship also seems to be roughly linear.

In a predator - prey relationship, when the number of wolves (predators) increases, they will hunt more bison, so the number of bison (prey) will decrease. Conversely, if the number of wolves decreases, the bison population can increase as there is less predation. So we expect a negative association between the number of wolves and the number of bison.

Answer:

There is a positive, linear association between height and shoe size. As height increases, shoe size tends to increase.

Exercise 2: Running (Distance Run vs. Average Running Speed) Relationship
