When the null assumption is ρ 0 = 0, independent variables, and X and Y have bivariate normal distribution or the sample size is large, then you may use the t-test. When ρ 0 ≠ 0, the sample distribution will not be symmetrical, hence you can't use the t distribution. In this case, you should use the Fisher transformation to transform the distribution. ear hospital bristol
