In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
sample size = 18
significance level = 0.01
Step 02:
correlation coefficient:
we must analyze the table to find the solution:
n = 18:
df = 18 - 2 = 16
p = 0.01
correlation coefficient = 0.590
The answer is:
correlation coefficient = 0.590
