i. The basic question in testing the significance of rho is to see if there is zero correlation in the population from which the sample was selected. ii. A t test is used to test the significance of the coefficient of correlation. iii. When testing the strength of the relationship between two variables, the alternate hypothesis is: H₀: $\rho$ $\neq$ 0. A) (i), (ii), and (iii) are all correct statements. B) (i) and (ii) are correct statements but not (iii). C) (i) and (iii) are correct statements but not (ii). D) (ii) and (iii) are correct statements but not (i). E) (i), (ii), and (iii) are all false statements.

All statements are correct. Statement i correctly identifies the purpose of testing the significance of rho (ρ), which is to determine if there is a non-zero correlation in the population. Statement ii accurately describes the use of a t-test to test the significance of the correlation coefficient. Statement iii, despite the formatting issues, intends to state that the alternate hypothesis in testing the relationship between two variables is that the correlation coefficient (ρ) is not equal to zero, which is a correct representation of the alternate hypothesis in correlation significance testing.
