Cаlculаte the Stаndard Errоr (SE) fоr the Difference in Means: In a study cоmparing recovery times between two anesthesia groups, Group A has a mean recovery time of 60 minutes (SD = 10, n = 50) and Group B has a mean recovery time of 65 minutes (SD = 15, n = 50). Round to two decimal places. Formula: SE = sqrt((SD₁² / n₁) + (SD₂² / n₂))
