Step-by-step explanation:
The correlation coefficient helps us understand the relationship between variables.
A positive correlation is a positive number. A negative correlation is a negative number.
We can automatically eliminate choices B and D because they are negative, but we are looking for a positive correlation.
A number closer to 1 indicates a strong correlation. If the number is closer to 0, it's weak.
The two choices left are:
- <u>A. r=0.17454 </u>
- C. r= 0.98264
C is very close to 1, so it's a strong correlation.
We want to find the weak one, which must be A because it is closer to 0.
