Mathematics · P-Value and Statistical Significance
A researcher conducts three independent statistical tests to evaluate different interventions. The probability of obtaining results at least as extreme as those observed, assuming the null hypothesis is true (the P-value), for the three tests are 0.042, 0.065, and 0.014. Using a commonly set significance level (α) threshold of 0.05, calculate the sum of the P-values for the tests that successfully determine statistical significance (where the null hypothesis can be rejected).
