As the sample size (i.e., the number of subjects) decreases, the correlation coefficient must O A) become positive (i.e., become stronger) in order to accept the null hypothesis. O B) decrease in size (i.e., become weaker) in order to reject the null hypothesis. C) increase in size (i.e., become stronger) in order to accept the null hypothesis. D) increase in size (i.e., become stronger) in order to reject the null hypothesis
