A product manager for an inexpensive shampoo product was concerned because of declining sales. The manager felt that in blind product testing there would be no difference or possibly even a preference by consumers for the inexpensive shampoo over the expensive brand name alternative. The product manager decides to test this hypothesis. If the inexpensive shampoo is given by $\pi$_I and the expensive shampoo by $\pi$_E, the correct hypotheses for this situation are A) H₀ : $\pi$_I = $\pi$_E, H_a : $\pi$_I $\pi$_E. B) H₀ : $\pi$_I = .50, H_a : $\pi$_I $\neq$ .50. C) H₀ : $\pi$_I
