Question

question 8 of 10 which of these is not a possible r - value? a. -0.1 b. -0.75 c. 1.2 d. 0.5

Explanation:

Step1: Recall r - value range

The correlation coefficient \(r\) has a range of \(- 1\leq r\leq1\).

Step2: Check each option

A. \(-0.1\) is in the range \(-1\leq r\leq1\).
B. \(-0.75\) is in the range \(-1\leq r\leq1\).
C. \(1.2>1\), so it is not in the range \(-1\leq r\leq1\).
D. \(0.5\) is in the range \(-1\leq r\leq1\).

Answer:

C. 1.2
