Males: n = 109,p_M = 0.422018 Females: n = 52,p_F = 0.25
p_M - p_F = 0.172018 Z = 2.11825
-Referring to Table 10-8,to determine if a difference exists in the taste preferences of men and women,give the correct alternative hypothesis that Pepsi would test.

• A)H₁ : μ_M - μ_F ≠ 0
• B)H₁ : μ_M - μ_F > 0
• C)H₁ : π_M - π_F ≠ 0
• D)H₁ : π_M - π_F = 0
