Explain the result of a Type I error.

Quizplus · Accepted Answer

A Type I error occurs when the null hypothesis (H0) is rejected when it is actually true. In this context, it means the manufacturer incorrectly concludes that the mean battery life has increased (is greater than 8.8 hours) when in reality, it has not changed and remains at 8.8 hours.
