source: time magazine, march 24, 2003
a. positive; as time goes on, more women are in the army.
b. no correlation
c. negative; as time goes on, fewer women are in the army.
d. negative; as time goes on, more women are in the army.

Explanation:

Step1: Analyze the trend

As the year increases (from 1981 to 1991 to 2001), the percentage of women in the army (the y - value) also increases.

Step2: Recall correlation definitions

A positive correlation means that as one variable (in this case, year) increases, the other variable (percentage of women in the army) also increases. A negative correlation means that as one variable increases, the other decreases. No correlation means there is no consistent relationship.

Answer:

A. positive; as time goes on, more women are in the army.
