See tests for equivalence stats.stackexchange.com/tags/tost/info – Alexis SpletStatistics A hypothesis test is to be performed for a population mean with null hypothesis of H0: u=u0 . The test statistic used will be z= x - u0 / o / square root of n.. Find the critical value (s) for a two-tailed test with α = 0.02 and draw a graph that illustrates your answer.

SpletSpecifically, the four steps involved in using the critical value approach to conducting any hypothesis test are: Specify the null and alternative hypotheses. Using the sample data and assuming the null hypothesis is true, calculate the value of the test statistic. The null hypothesis is the claim that there’s no effect in the population. If the sample provides enough evidence against the claim that there’s no effect in the population (p ≤ α), then we can reject the null hypothesis. Otherwise, we fail to reject the null hypothesis. Although “fail to reject” may sound awkward, it’s the … Prikaži več The null and alternative hypotheses offer competing answers to your research question.

SpletThe simulate_precipitation_null() function generates a single simulated sample of precipitation data that adheres to the null hypothesis, which states that there is no difference in average precipitation between two regions. This function uses the mean and standard deviation of each region, as well as the sample sizes, to generate the simulated … SpletSuppose that we reject a null hypothesis at the 0.05 level of significance. Then for which of the following α-values do we also reject the null hypothesis? a. 0.06 b. 0.04 c. 0.03 d. 0.02 ____ 11.
