True or false The practical significance of a decision rejecting the null hypothesis should always be considered with every statistical test outcome.
Which one the following statements is false about the null hypothesis? It is the hypothesis that the observed correlation is the result of random fluctuation. The likelihood of observing the results that we observed if this hypothesis is true, is the p-value. It is the hypothesis that would be wrong in case our causal hypothesis is true. The hypothesis that our causal explanation is true and explains the observed correlation.
1) In hypothesis testing, the region of rejection of the null hypothesis will always be smaller than the region of acceptance of the null hypothesis. True or False? One-sample tests use data drawn from a single sample to test that the sample comes from a specified population. True or False? A study of more than 20,000 mothers of newborns revealed a 10% greater likelihood of purchase by mothers of boys versus mothers of girls. The null hypothesis is: "Mothers of...

Question 1 For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc True False Question 2 For ANOVA: the alternative hypothesis is: Mu1 ≠Mu2 ≠Mu3......etc. True False Question 3 Both ANOVA and Chi square tests are always right tail tests True False Question 4 For ANOVA, you only complete a Tukey's means comparisons test if the overall F* value was significant (i.e., p<0.05) True False Question 5 Both F and Chi Square distributions vary with df True False Question...
