Question

Group of answer choices

r-critical = .537, Reject H0 (Conclude there is a correlation in the population)

r-critical = .561, Reject H0 (Conclude there is a correlation in the population)

r-critical = .537, Fail to Reject H0 (Conclude there is no correlation in the population)

r-critical = .561, Fail to Reject H0 (Conclude there is no correlation in the population)

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
