5 women in a study to decrease their reaction time had a mean of 1.5 seconds after training. The population mean is 1.8 seconds with a standard deviation of .5. Using a .05 significance level, what can you conclude about this training? Work through all hypothesis testing steps (remember, we need to find σM as we can’t just use σ) to answer: • Does the experimental group have a significantly lower mean than the comparison group? • Indicate whether you reject or fail to reject the null hypothesis and give a brief explanation of interpretation for your conclusion.
