We want to make an hypothesis test for the mean value of a normal population with known variance , using a sample of size that has sample mean value equal to .
Calculate the -value.
Make the test with significance level about if the population mean value from which the sample comes from is greater than using the -value.
For the first one, about the -value, do we have to calculate ?
And for the second we have to check the -value with the significance level, right?
