and the questions at the end of all the information. --> I cant tell what goes where. J M-C In
Unit 3 you tested 5 different hypotheses using the database from Unit 2. Provide a summary of your findings. Address each hypothesis you tested (2 - 3 pages) Hypotheses
Set 1 Ho: average overall job satisfaction = 4.5 HA: average overall job satisfaction
? 4.5 Survey respondents rated their satisfaction levels with their jobs on a scale of 1 to 7, with 7 being the most
satisfied. The null hypothesis is that the mean of the 288 responses to this survey question would equal 4.5 Using the data
given, however, simple mean job satisfaction from a sample of 288 employees was found to be 4.33. The variance was calculated to be 1.8611.
Using this information to calculate student t returns a value of 2.11. A 95% confidence interval (p = 0.05) requires a critical value of ? 1.97, well
less than calculated t of 2.13. The z score for 2.11 is .4834, which is used to calculate a risk. Alpha risk
thus is 0.5 - 0.4834 = 0.0166, or 1.7%. This 1.7% risk represents the risk that we reject H0 when it should have been accepted.
Even though there is some measure of risk that we have rejected H0 when it should have been accepted, we still have the disparate critical value that
