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).
We have to check whether n = 2 and r = 1, are the data significant or non-significant and explain it.
Step-by-step explanation
Step 1.
When there are only two data points, the r-value will always be 1 or –1, because the pattern is always linear. Since the number of data points is small data is non-significant.
