Construct an interval estimate for the given parameter using the given sample statistic and margin of error. For μ1-μ2, using x¯1-x¯2=8 with margin of error 8 .

CI = (0, 8)

Step-by-step explanation: Confidence interval for difference between mean is given below as

Lower limit

= (x1 - x2) + margin of error

Upper limit

= (x1 - x2) - margin of error

where x1 - x2 = 8 and margin of error = 8

For lower limit,

= 8 - 8 = 0

For upper limit

= 8 + 8 = 16

Hence CI = (0, 8)

expression #3 is not equivalent. the others are.
