The significance level is at 0.01 and the p-value is at 0.01. The researcher should reject the null hypothesis. The potential error that the researcher is making is a type II error (type II error occurs when there is non-rejection of a false null hypothesis)

A researcher selects an alpha level of 0.15 for a study. What does this indicate about the statistical analysis of the study? the researcher is willing to accept a 15% chance that the null hypothesis will be rejected incorrectly the study results are likely to reveal a high level of clinical significance of the alternative hypthesis there is a high probability of making a type one error the researcher is willing to accept an 85% chance that the null hypothesis...
