Random sampling is a crucial assumption for hypothesis testing of the Pearson correlation coefficient because it ensures that the sample is representative of the population and reduces the risk of bias. The other choices (A, C, and D) are incorrect assumptions because the Pearson correlation coefficient is used for continuous variables, not ordinal scores, and it does not assume that either variable comes from a normal distribution.
