Lesson 6.1.1 R&P 6-4 to 6-9

6-4) a. Sam collected data by measuring the pencils of her classmates. She recorded the length of the painted part of each pencil and its weight. Her data is shown on the graph.

Describe the association between weight and length of the pencil. Remember to describe the form, direction, strength, and outliers.

• The association between the weight and length of the pencil is a strong, positive, non-linear association with an outlier at (2.2, 4.5)

• The association between the weight and length of the pencil is a strong, negative, linear association with an outlier at (2.2, 4.5)

• The association between the weight and length of the pencil is a moderate, positive, linear association with an outlier at (2.2, 4.5)

• The association between the weight and length of the pencil is a strong, positive, linear association with an outlier at (2.2, 4.5)

6-4) b. Sam collected data by measuring the pencils of her classmates. She recorded the length of the painted part of each pencil and its weight. Her data is shown on the graph.

Make a conjecture (guess) about why Sam's data had an outlier.

• Length increases 1.4 cm every 1g the weight increases.

• Weight increases 1.4g every 1 cm the length increases.

• For every 1 cm the length increases, the weight increases 0.25g.

• For every 1g the weight increases, the length increases 0.25cm.

• When the pencil has no paint it will weigh 1.4g

• When the pencil doesn't weigh anything, the paint will be 1.4 cm long.

• When the pencil has no paint, it will weigh 0.25g

• When the pencil doesn't weigh anything, the paint will be 0.25 cm long.
