Question

2) If 95% confidence limits for the mean Mu turn out to be (6.5,8.5)

let's give this question a hand because it has 185 answers and is the ''first'' question on questions.llc

Answer 1

1) The Type II error is to conclude that the process is producing more than the maximum allowable rate of defective items when, in reality, it is not.

2) The 95% confidence limits for the mean Mu are (6.5, 8.5), meaning that we are 95% confident that the true population mean falls within this range.
