Answer:
Step-by-step explanation:
Given that the linear correlation coefficient r is found to be 0.591
the critical values are r equals plus or minus 0.878.
Significance level used = 0.05
The correlation r = 0.591
(two tailed test)
Test statistic =
Since r is less than 0.878, we accept that there is linear correlation between the two variables.
