Using the 10 steps for testing hypotheses (list all the ten steps and provide the answer under each), determine if the null hypothesis can be rejected or fail to be rejected.  

•1. State the null hypothesis (H0)

•2. State the research or alternate hypothesis (Ha) (H1)

•3. Identify H1 as one or two-tailed

•4. Specify the alpha level (level of significance)

•5. Determine appropriate statistical test (show work, can use SPSS)

•6. Specify the degrees of freedom (not with the z test) (Show work)

•7. Identify the Critical Value (zcritor tcrit) (Show work)

•8. State decision (rejection) rule (use normal distribution curve)

•If the absolute value of the calculated score is greater than critical value, then the null hypothesis is rejected

•If the absolute value of the calculated score is less than the critical value, then there is a failure to reject the null hypothesis

•9. Calculate z or t (zobtor tobt) and show it on the normal distribution curve

•10. State the meaning of the results in a  complete sentence

Answer 1

The hypothesis being tested is:

H₀: µ₁ = µ₂

H₁: µ₁ ≠ µ₂

This is a two-tailed test.

The level of significance is 0.05.

The appropriate statistical test is an Independent samples t-test.

The degree of freedom is 28.

The critical value is 2.05.

Data is not in the copy-text type format.

As per the Chegg answering guide, we have the option to answer only the first four sub-parts of a question in case of multiple parts. If you want to get the answers for the rest of the parts, please post the question in a new post.

Please give me a thumbs-up if this helps you out. Thank you! :)
