Question number 6.

The sample mean doesn’t represent the raw score population on which the sampling distribution is based

Note : if the z score of sample mean is larger than critical value that means the z score is in the rejection region so we conclude that the sample mean doesn’t represent the raw population . We don’t conclude with 100% confidence . There is some probability that our conclusion is wrong. That is type 1 error, rejecting a true hypothesis. The probability of type 1 error is small .
