Calculate the Standard Error (SE) for the Difference in Means: In a study comparing 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))

Determine the t-value for a Two-Sample t-Test: Using the data from the previous question with an SE of 2.55, calculate the t-value to test the difference in recovery times between the two groups. Round to two decimal places, and assume t value is positive. Formula: t = (Mean₁ − Mean₂) / SE

Calculate the Standard Error (SE) of the Difference in Proportion for Complications: In a comparison of two anesthetics, 30% of patients in Group A experienced complications (n=100), while 20% in Group B did (n=100). Calculate the SE for the difference in proportion. Round to the thousandths place. Formula: SE = √[(p₁ × (1 − p₁) ÷ n₁) + (p₂ × (1 − p₂) ÷ n₂)]
