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?

-0.361 and 0.361

0.306

0.361

-0.306 and 0.306

Solution

P-value is the probability of the occurence of the test statistic in the critical region defined by it. that is it is the probability of the falling of this value in the area to the right of the p-value which in our example is 0.05

the corresponding critical cutoof values would be

-0.361 and 0.361
