If we assume that the conditions for correlation are met, which of the following are true? If false, explain briefly. Complete parts (a) through (c) below. 0) 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. O B. This statement is false. It is a weak, negative association. A negative correlation coefficient shows a weak association. OC. 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. O D. This statement is false. It is a weak, negative association. The smaller the correlation coefficient is, the weaker the association. b) Multiplying every value of x by 2 will double the correlation. Is this statement true? If false, explain briefly. Choose the corect answer below. A. This statement is true. O B. This statement is false. It will quadruple it since 2 squared is 4. OC. This statement is false. It will not change the correlation. 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.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
