1.

Use the Excel file "Bear Measurements." Is there a statistically significant relationship between the variables of Month and Weight?

Select one:

a.

Even without knowing the critical value for r, there is a high probability that the variables have a statistically significant relationship.

b.

If a scatterplot is used to visually inspect the linear relationship, there is no need to consider the critical value forr.

c.

Even without knowing the critical value for r, there is a low probability that the variables have a statistically significant relationship.

2.

Use the Excel file to calculate Bear Head Width and Bear Neck Size. What is a correct interpretation of the result?

Select one:

a.

There is a strong positive relationship. Therefore, we know that asBear Head Width increases, we expect to see Bear Neck Size increase.

b.

There is a strong negative relationship. Therefore, we know that asBear Head Width increases, it causes Bear Neck Size to decrease.

c.

There is a strong negative relationship. Therefore, we know that asBear Head Width increases, we expect to see Bear Neck Size decrease.
