Hypothesis testing for the population mean.
A random sample of n = 81 measurements to test Ho: μ = 40 versus Ha: μ ≠ 42, x-bar = 34 and σ = 18
Analyse the value of the test statistic z: [ ]
What is the rejection point at α = .10 and indicate if you would accept or reject Ho? [ ]
What is the rejection point at α = .05 and indicate if you would accept or reject Ho? [ ]
What is the rejection point at α = .01 and indicate if you would accept or reject Ho? [ ]
What is the rejection point at α = .001 and indicate if you would accept or reject Ho? [ ]
Compute the p-value: [ ] Do any of your above conclusions change on acceptance or rejection of Ho? [ ]
How much evidence is there that the mean composite satisfaction does not equal 40? [ ]
