A 95 percent confidence interval for the proportion difference p₁ -p2 was calculated to be (-0.12, 0.17). Which of the following conclusions is supported by the interval? (A) There is evidence to conclude that p₁ > p2 because 0.17 is greater than -0.12. (B) There is evidence to conclude that p2 > p₁ because 0.17 is greater than 0.12. (C) There is evidence to conclude that p₁> p2 because the range of positive values in the interval is greater than the range of negative values. (D) (E) There is evidence to conclude that p2 > P₁ because the range of positive values in the interval is greater than the range of negative values. There is not sufficient evidence to determine which proportion is greater.

(C) There is evidence to conclude that p₁ > p2 because the range of positive values in the interval is greater than the range of negative values. (D) (E) There is evidence to conclude that p2 > P₁ because the range of positive values in the interval is greater than the range of negative values. There is not sufficient evidence to determine which proportion is greater.
