- A decision to reject the null hypothesis means you have demonstrated that the treatment has no effect
Step by step
Solved in 2 steps
- Conduct a test of the null hypothesis for both independent variable and interpret your finding. You do not have to calculate anything by hand here; use excel output.You recently completed an experiment concerning the effects of carbs on happiness. One group of 11 people are assigned a high carb diet, another group of 11 people are assigned a moderate-high carb diet, another group of 11 people are assigned a moderate-low carb diet, and a final group of 11 people are assigned a low carb diet. If I find that I fail to reject the null hypothesis, what might my next step be? Group of answer choices Change my analysis and alpha to make the finding significant and then run post-hoc tests. 1. Run multiple dependent measures t-tests to see if there are any significant differences between particular groups 2. Run multiple independent samples t-tests to see if there are any significant differences between particular groups 3. Change my hypothesis to see if I can find something significant with a different hypothesis for this study 4. Run home and binge-watch Bridgerton because there is nothing else that should be done statisticallyYou complete a hypothesis test using alpha = .05 and based on the evidence from the sample, your decision is to fail to reject the null hypothesis. If the treatment actually does have an effect, which of the following is true?
- If we fail to reject the null hypothesis when the alternative hypothesis is true, we have made a O type a error. O type B error. O type I error. O type II error. O correct decision.If we reject the null hypothesis when testing to see if a certain treatment has an effect, it means the treatment does have an effect. True FalseThe clinical trial for a new drug results in a p-value of 0.15. What decision should the scientists make? We accept the alternative hypothesis that the drug does work. We reject the alternative hypothesis that the drug does work. We accept the null hypothesis that the drug doesn't work. We cannot reject the null hypothesis that the drug doesn't work.
- A researcher selects a sample and administers a treatment for anxiety to the individuals in the sample. If the sample is used for a hypothesis test, what does the null hypothesis (Ho) put forth about the treatment? O The treatment has an effect on anxiety. O The treatment divides each anxiety score by a constant. O The treatment multiplies each anxiety score by a constant. The treatment has no effect on anxiety.Could you please help me out with this question… Does ivy grow better in areas with more sun versus in shady areas? Formulate one null (H0) and one alternative (H1) hypothesis.Type-II error is? A. Rejecting the null hypothesis when it is actually true B. Not rejecting the null hypothesis when its actually false C. Accepting the null hypothesis when its actually false D. Rejecting the alternative hypothesis it is actually false
- In most experiments, researchers would prefer to fail to reject the null hypothesis. Is this statement True or False?A researcher hypothesizes that Drug A is more effective than Drug B. In conducting an analysis to test this hypothesis, how should the null hypothesis be stated?Type I error is when you end up rejecting the null hypothesis as a result of the statistical testing, when in fact the null hypothesis is actually ____."
