Question

1.What comparison is being made in a hypothesis test?

a.​Research results from a population and a hypothesis about a sample

​b.Research results from a population and a hypothesis about the population

​c.Research results from a sample and a hypothesis about a population

​d.Research results from a sample and a hypothesis about the sample

2.If a sample is given a treatment and used for a hypothesis test, 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 to the individuals in the sample. If the sample is used for a hypothesis 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 can determine if we have statistical significance.

d.All answers are correct

5.The critical boundaries for a hypothesis test are z = +1.96 and -1.96. If the z-score for the sample data is z = -1.90, what is the correct statistical decision?​

a.Reject H₀

​b.Reject H₁

​c.Fail to reject H₁

​d.Fail to reject H₀

Answer 1

1) Option C

The Logic of Hypothesis Testing As simply communicated, the explanation of hypothesis testing in estimations incorporates four phases. specific the Hypothesis: we are going to normally specific a speculation (surmise) many open. frequently the speculation considerations the estimation of an open limit.

2) Option A

Because decree regarding the estimation of associate degree open limit, within the occasion of two speculations, the declaration thought to be real is assumed in light-weight of the actual fact that the invalid hypothesis H0 and what is more the incompatible clarification is assumed on the grounds that the elective theory and Ha.

3)Option B

It is measurable by the divisor of the z-score investigate live. traditional|the conventional} partition between A model mean M and what is more the open mean µ that will be standard if H0 was legitimate. the occasion mean ought to be closed eighty and will lead you to disregard to make a case for the invalid theory.

4)Option B

Before you run any quantitative investigate, you must abdomen muscle initio opt for your alpha level, that is likewise referred to as the "significance level. By definition, the alpha level is that the chance of dismissing the invalid theory once the invalid speculation is valid. Understanding: it is the chance of creating associate degree peripheral alternative.

5) Option B
