What is the critical r value for a level of significance of 0.01? O 0.934 O 0.745 O 0.980 0 0.259 O 0.333 Question 14 14. What do you conclude about the data? O the calculated r value is greater than the critical r value so the correlation is significant. O the calculated r value is greater than the critical r value so the correlation is not significant. O the calculated r value is not greater than the critical r value so the correlation is significant. O the calculated r value is not greater than the critical r value so the correlation is not significant.A high school psychologist was concerned about the equivalency of two types of standardized tests given to students as part of their college entrance exams.
