Systolic and diastolic blood pressures were measured in 10 subjects. With these, a Pearson and a Spearman correlation coefficient were calculated. Both were found to be equal to 0.65. For both, the null hypothesis is tested that the population correlation coefficient is equal to 0, against the two-way alternative, with a risk of α = 0.05. Which of the two following statements are TRUE? 1: The Pearson correlation coefficient ρP deviates significantly from 0.†. 2: The Spearman rank correlation coefficient ρS deviates significantly from 0.
