a.​Research results from a population and a hypothesis about asample
​b.Research results from a population and a hypothesis about thepopulation
​c.Research results from a sample and a hypothesis about apopulation
​d.Research results from a sample and a hypothesis about thesample
2.If a sample is given a treatment and used for a hypothesistest, what would the null hypothesis (H0) say?​
​a.The treatment causes a change in the scores
​b.The treatment will have no effect on the scores
​c.The treatment multiplies each score by a constant
​d.The treatment adds a constant to each score
3.A researcher selects a sample and administers a treatment tothe individuals in the sample. If the sample is used for ahypothesis test, what does the alternative hypothesis(H1) say about the treatment?
​a.The treatment multiplies each score by a constant.
​b.The treatment causes a change in the scores.
c.​The treatment has no effect on the scores.
​d.The treatment adds a constant to each score
4.The alpha level is
a.set prior to doing the research.
b.the significance level of a test.
c.our criterion to compare are actual p-value to so we candetermine if we have statistical significance.
d.All answers are correct
