Answer 1

Answer:

• c. 1.2

Explanation:

The possible values of r, the correlation coefficient of a sequence of values, are  -1  ≤ r ≤ 1.

This is, r cannot be either less than - 1 or greater than 1.

A correlation coefficient r = -0.1 denotes a very weak negative correlation. A correlation coefficient r = - 0.75 means a strong negative correlation. A correlation coefficient r = 0.5 indicates a moderate positive correlation. A value of r = 1.2 is not possible: r can neve be greater than 1.
