Final Answer :
C
Explanation :
The t test is often used to examine the significance of a correlation coefficient. This involves transforming the correlation coefficient into a t statistic, which can then be used to test the hypothesis that there is no correlation (i.e., the population correlation coefficient is zero) against the alternative that there is a non-zero correlation.
