A hypothesis test is conducted at the .05 level of significance to test whether or not the population correlation is zero. If the sample consists of 25 observations and the correlation coefficient is 0.60, what is the computed value of the test statistic? Round to two decimal places.
A) 1.96
B) 2.07
C) 2.94
D) 3.60

The test statistic for testing the significance of a correlation coefficient is calculated using the formula: t = r√(n-2) / √(1-r²), where r is the sample correlation coefficient and n is the sample size. Substituting the given values: t = 0.60√(25-2) / √(1-0.60²) = 3.60.
