Example 8.4 An automobile model is known to sustain no visible damage 25% of the time in 10-mph crash tests. A modified bumper design has been proposed in an effort to increase this percentage. Let p denote the proportion of all 10-mph crashes with this new bumper that result in no visible damage. The hypotheses to be tested are Ho: P = 0.25 (no improvement) versus Ha: p ? ? 0.25. The test will be based on an experiment involving...
