Ime uiat the conditions for correlation are met, which of the following are true? If false, explain briefly. Complete parts (a) through (c) below. a) A correlation of -0.98 indicates a strong, negative association. Is this statement true? If false, explain briefly. Choose the correct answer below. O A. This statement is true. OB. This statement is false. It is a weak, negative association. Correlations range from - 100 to 100. Since this value is barely - 1, this is weak. OC. This statement is false. It is a weak, negative association. The smaller the correlation coefficient is, the weaker the association. O D. This statement is false. It is a weak, negative association. A negative correlation coefficient shows a weak association. b) Multiplying every value of x by 2 will double the correlation. Is this statement true? If false, explain briefly. Choose the correct answer below. O A. This statement is true. O B. This statement is false. It will not change the correlation. O C. This statement is false. It will quadruple it since 2 squared is 4. O D. This statement is false. It will divide the correlation by 2. c) The units of the correlation are the same as the units of y. Is this statement true? If false, explain briefly. Choose the correct answer below. O A. This statement is true O B. This statement is false. The units of the correlation are a combination of the units of y and the units of x O C. This statement is false. Correlations are measured in percentages. O D. This statement is false. Correlation has no units.
