Answer these

95%Cl for mean difference shows statistical significance for the observed result if: 0 At least one out oftwo means is included in the range. 0 If it includes the null value of zero. 0 It includes the null value of one. 0 It does not include null value of zero. 0 It does not include null value of one. There are 3 incorrect statements out of the following six. Please identify those. Three answers are required. If the Pearson correlation coefficient r between two variables is less than 0, then there is no relationship between the two variables. Normality assumption only applies if the test variable is continuous data (interval or ratio). Hypotheses (null and alternative/research) are written for the population and not for the sample. Sample only serves the purpose of testing those hypotheses. Post Hoc pair wise comparisons in ANOVA are appropriate when researcher has no specific hypothesis about which group or groups will differ from the others. Reliability is the degree to which a screening test measures what it is intended to measure. Type 2 error is made in hypothesis testing when false positive results are reported. 'Statistical inference' is a decision, estimate, prediction, or generalization about the population based on information contained in a sample
