Based on the correlation, there does not appear to be any relationship between high school girls' heights and their IQ scores. O Question 9 O B. As high school girls' heights increase, their IQ scores tend to increase. O C. Based on the correlation, there does not appear to be a linear relationship between high school girls' heights and their IQ scores. O Question 10 O D. Increases in high school girls' heights cause their IQ scores to decrease. O E. Increases in high school girls' heights cause their IQ scores to increase. O F. As high school girls' heights increase, their IQ scores tend to decrease. O Question 11 (d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation coefficient. Let a = 0.01. O Question 12 The critical value is . Therefore, there sufficient evidence at the 1% level of significance to conclude that between high school girls' heights and their IQ scores. (Round to three decimal places as needed.)
