True or False? A hypothesis test is conducted at to test whether the population correlation coefficient is zero. If the sample size is 25 and the sample correlation coefficient is 0.6, then the critical values of the student t that define the upper and lower tail rejection areas are 2.069 and -2.069, respectively.
