Webb24 jan. 2024 · Conclusion. The p-value and critical value are two key pieces of statistical information that can be used to help you understand the results of your research. The p value is a measure of the probability that your results are due to chance, and the critical value is the point at which your results are considered statistically significant.

WebbAlternative Hypothesis. Formulating the competing hypothesis. 1.) Identify the relevant population parameter of interest. 2.) Determine whether it is a one-two tailed test. 3.) Include some form of the equalitiy sign in the null hypothesis and use the alternative hypothesis to establish a claim. We would conduct a hypothesis test to determine ...
