When the sample size n is greater than 30 and Spearman rank correlation coefficient r is calculated, it approximately follows a normal distribution with mean 0 and standard deviation of 1/sqrt(n-1). Therefore, the answer is C, with mean 0 and standard deviation. It is important to note that the options B and D both have missing values for the standard deviation, making them incorrect choices.
