How do I set up H0 and HA and perform 'the test' using SPSS?
Ho or null hypothesis is usually when you estimate a parameter to be equal to some fixed value like in 1-sample t-test, 1-sample z-test, 1-sample proportion test,
it could also be that you test for equality of two parameters like in 2-sample t-test or z-test where null hypothesis is
mu1 = mu2
or sigma^2_1 = sigma^2_2
Alternate hypothesis can be left-tailed, right-tailed or two-tailed
For example in 1-sample t-test
Ha: mu > 25 (say) (right-tailed)
Ha: mu < 25 (left-tailed)
Ha: mu
25 {two-tailed)
each of test can be done on SPSS
Since you have not specified which test you want to conduct
say you want to conduct 1-sample t-test
analyze -> compare means -> one sample t-test
similarly you can conduct other tests also
Perform a one-tailed test. Set up H0 and Ha. Compute test statistic and p-value. Draw conclusions. #1. A Gallup survey conducted April 2–11, 2018, found that 152 out of 1015 American adults mentioned immigration/illegal aliens as the most important problem facing the nation. An earlier survey conducted in February 2011 found that 108 out of 978 American adults mentioned immigration/illegal aliens as the most important problem facing the nation. Can we conclude that the percentage of all American adults who...
Perform a one-tailed test. Set up H0 and Ha. Compute test statistic and p-value. Draw conclusions. For both questions. #1.

How do you perform data analysis in SPSS? (1 point) analyze tocl
Test H0 : p = 0.75 vs Ha : p ≠ 0.75 using the sample results p^ = 0.69 with n = 120
You will perform a significance test of H0: μ = 19 based on an SRS of n = 25. Assume that σ = 13. Step 1: If x = 23, what is the test statistic z to 2 decimal places? Step 2: What is the P-value if Ha: μ > 19? Give your answer to 4 decimal places. Step 3: What is the P-value if Ha: μ ≠ 19? Give your answer to 4 decimal places.
8. Below is a hypothesis test set up by a student who recently took introductory statistics: H0: x = 5 HA: x ≠ 5 The sample mean of 100 cases used to implement the hypothesis test is x = 4.2. Which of the following statements are accurate? This is a one-sided hypothesis test. There is an error in how these hypotheses were constructed. It would be reasonable to swap "<" for "≠" in the alternative hypothesis. i only ii only...
set-up each hypothesis test (Steps 1-3) only. DO NOT PERFORM A COMPLETE HYPOTHESIS TEST! Be sure to properly label all variables (z,t, etc...) and parameters(1.0, etc..). Do not only write a numbers 3.) The average number of series streamed per year for households is reported to be 8.5 with a standard deviation of 2.1. In random sample of 30 households, the standard deviation in series streamed was 3.5. At a = 0.10, is there evidence to suggest that the standard...
