Given information
Given that, a random sample of ten professional athletes produced the following data where x is the number of endorsements the player has and y is the amount of money made (in millions of dollars).
When n = 100 and r = -0.89, we have to check whether is there a significant correlation or not and explain it.
Step-by-step explanation
Step 1.
The correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatter plot. The value of r is always between +1 and –1.
If,
- r-value is positive, which means that there is a positive correlation.
- r-value is negative, which means that there is a negative correlation.
- r-value is zero, which means that there is no linear correlation.
