A pharmacologist measured the concentration of oxytocin in the brains of several rats. The mean concentration was 10,563 ng/mL and the standard deviation was 35 ng/mL. Based on the information provided, answer the following and include all calculations: 1. What was the standard error of the mean if 5 rats were measured? (2pt) 2. What was the standard error of the mean if 28 rats were measured? (2pt) 3. What was the standard error of the mean if 73 rats were measured? (2pt)
