A correlation is computed using data from 30 people. What is the critical cutoff for a two-tailed hypothesis test with a p level of 0.05?

Question 14 options:

0.306

0.361

–0.306 and 0.306

–0.361 and 0.361

Solution

degrees of freedom in this case is n-2 = 28

using a critical r value table, we can see the critical value is 0.361 (we have to put the sign ourself)

–0.306 and 0.306
