All of the listed options (probability, level of significance, and decision to retain or reject the null hypothesis) are key components of hypothesis testing. The researcher's decision is based on a probability, specifically the p-value, which is compared to the level of significance (often set at 0.05). If the p-value is lower than the level of significance, the researcher can reject the null hypothesis. If it is not, the null hypothesis is retained. Therefore, all options are correct.
