Which of these is not a possible r-value?A.0.2B.–0.5C.1.75D.–0.1SUBMITarrow_backPREVIOUS

Break Down the Problem

1. Identify possible values for r-value.
2. Distinguish the r-value range and find which option is outside that range.

Relevant Concepts

• The r-value, or correlation coefficient, is a statistical measure that ranges from -1 to 1.
• Values below -1 or above 1 are not possible for r-values.

Analysis and Detail

3. Evaluate the options provided:
   • A. 0.2: This value falls within the range of r-values (-1 to 1).
   • B. -0.5: This value also falls within the range of r-values (-1 to 1).
   • C. 1.75: This value exceeds the upper limit of the r-value range (1).
   • D. -0.1: This value falls within the range of r-values (-1 to 1).

Verify and Summarize

4. Among the options analyzed, the only value that is not a possible r-value is 1.75, as it exceeds the permissible range.

Final Answer

The option that is not a possible r-value is C. 1.75.
