Step 1: State the Hypothesis Ha: # 100 hrs Ho:ĩ = 100 hrs Step 2: Level of Significance a= 0.05 (Two – tailed) Step 3: Test to be used Step 4: Calculations Z - test i = 100 hrs H- 980 hrs n= 100 bulbs a = 100 hrs 100 – 980 100/V100 From the normal probability distribution table P(z = 2) = 0.0455 Rejection Region: P(Z)s 0.025 or P(Z) 20.975 Acceptance Region: 0.025 < P(Z) <0.0975 Since P(z = 2) = 0.0455 is within the acceptance region, we accept the nul hypothesis. Step 5: Conclusion | Therefore the sample mean is significantly different from 1000 hours
