Step-by-step explanation:
Answer: CI = (0, 8)
Step-by-step explanation: The confidence interval for the difference in means is given as
Lower limit
= (x1 - x2) + margin of error
Upper limit
= (x1 - x2) - margin of error
Where x1 - x2 = 8 and the margin of error = 8
For the lower limit,
= 8 - 8 = 0
For the upper limit
= 8 + 8 = 16
Thus, CI = (0, 8)
