A company would like to examine the linear relationship between the age and credit score of an individual. The following table shows the credit scores and ages of 5 randomly selected people. These data have a sample correlation coefficient, rounded to three decimal places, of
0.973.
Using this data and
α=0.10,
test if the population correlation coefficient between a person's age and credit score is different than zero. What conclusions can you draw?
