If the t-test is used to test the significance of a correlation coefficient,the null hypothesis is:
A)r = +1.00
B)r = 0
C)r = -1.00
D)r = 100

Question

The null hypothesis for testing the significance of a correlation coefficient is that there is no significant correlation between the two variables, which is represented by a correlation coefficient of 0. The other choices are either incorrect or redundant, as r = +1.00 and r = -1.00 represent perfect positive and negative correlation, respectively, and r = 100 is not a valid correlation coefficient value.
