As we can see, the medical treatment is truly effective but a researcher does not reject the null hypothesis that implies that the researcher has made a type 1 error because null hypothesis states that medical treatment is not effective and the researcher does not reject the null hypothesis, it means the researcher has accepted the false null hypothesis because medical treatment is in fact effective. Type one error occurs when we accept the false null hypothesis.

You set up a two-sided hypothesis test for a population mean μ with a null hypothesis...
You set up a two-sided hypothesis test for a population mean μ with a null hypothesis of H0:μ=100. You chose a significance level of α=0.05. The p-value calculated from the data is 0.12, and hence you failed to reject the null hypothesis. Suppose that after your analysis was completed and published, an expert informed you that the true value of μ is 104. How would you describe the result of your analysis? A) A Type 1 error was made because...
