A new battery is expected to have a storage capacity of 60 ampere-hour (A h). A sample is tested, resulting in a 2-side confidence interval of (63 A h ≤ μ ≤ 72 A h) with 95 % Confidence. Which conclusion is correct?
The battery storage capacity is not significantly different than 60 A h, at a confidence level of 95 %
The battery storage capacity is significantly different than 60 A h, at a confidence level of 95 %
The battery storage capacity is significantly higher than 60 A h, at a confidence level of 95 %
The battery storage capacity is significantly lower than 60 A h, at a confidence level of 95 %
