Scatter Plots Part 2

Which scatter plot would be best described as a positive nonlinear association?

• 1

• 2

• 3

• 4

What type of association would the following situation have:

The size of a home and monthly utilities

• positive linear

• negative linear

• nonlinear

• no association

Select all terms that could be used to describe the association of the scatter plot.

• no association

• positive

• negative

• nonlinear

• linear

Choose the equation of the line of best fit.

• y=100x+0.5

• y=0.5x+100

• y=12.5x+100

• y=25x+100

Using the two points in red in the scatter plot, determine the slope.

• 750 feet

• 600 feet

• 875 feet

• 250 feet

• 17.6 mins

• 35,000 mins

• 2.4 mins

• 13.5 mins

Select all true statements about the scatter plot.

• The point (4,750) is an outlier

• The data is clustered between 2 and 3 days.

• The data indicates a positive linear trend.

• A reasonable estimate for an 8-day cruise is $720.

• The data indicates a nonlinear association.

Which line best fits the data?

• 1

• 2

• 3

• 4

Select the 2 true statements.

• The slope represents the increase in test score for each additional minute studied.

• The slope represents the test score when a student has not studied.

• The y-intercept means that a person that studied for 60 minutes made a score of 0 on the test.

• The y-intercept means that a person has studied for 0 minutes, the predicted score on the test is a 60.

• If a student studies for 30 minutes, it is expected that he/she will make a 90 on the test.
