Question

If n = 20, use a significance level of 0.01 to find the critical value for the linear correlation coefficient r.

Answer 1

Answer:

0.561

Step-by-step explanation:

To solve this problem we must resort to external information that I will leave attached with the answer, it is a table that for each value of n, gives us the critical values.

Returns the critical values ​​for both the significant levels of 0.01 and 0.05.

If we go to the table we know that when n = 20 and the significant level is 0.01, the corresponding critical value is: 0.561
