Why must we typically use the formula instead of using ó₁ and ó₂ when conducting a two-sample hypothesis test? A) because the standard deviations from the relevant populations (ó₁ and ó₂) are seldom known B) because ó₁ and ó₂ are based on the sampling distribution, which is biased C) because ó₁ and ó₂ can be used only for nominal level variables D) because ó₁ and ó₂ increase the risk of Type I error
