Appropriate hypotheses using appropriate data

Reference no: EM1397527

The wall thickness of 25 glass 2-liter bottles was measured by a quality control engineer. The sample mean was 4.058 mm and sample standard deviation was 0.081 mm. Suppose that it is important to demonstrate that the wall thickness exceeds 4.0 mm. Test appropriate hypotheses using these data. Draw conclusions at α= 0.05.
