Option B is correct = 4.082
Step-by-step explanation:
From the question, we have the following information;
Sample A, 60 people are randomly selected = $200 for textbook in one term.
Sample B:, 40 people are randomly selected = $180 for textbook in one term. Standard deviation of sample A and B =$20.
Difference in the average value= 200-180 = 20.
To calculate the standard error we have;
Standard error= SD/√number of sample.
Standard error= 20/√20 = 20/ 4.472
= 4...
