80% confidence interval with Maximum error is
(3.61, 3.79)
Step-by-step explanation:
Explanation
Given the mean of the sample ( x⁻) = 3.7
The maximum error = 0.09
80% confidence interval is determined by
( x⁻ - M.E , x⁻ + M.E)
( 3.7 - 0.09 , 3.7 +0.09)
(3.61 , 3.79)
Final -
80% confidence interval with Maximum error is
(3.61, 3.79)
