A manager claims that this is different in his department. A representative sample of 100 workers of the department were asked to estimate the number of days of work lost during the last year. The sample average was 17 and its standard deviation was 3. Use Z-test to test the researcher claim at a level of significance 0.05. 10 Marks Problem: Ho: H1: Decision Rule: Calculations: Sx= Z17= Decision: Interpretation Why did the researcher used Z-test?
