Use the GSS dataset to answer the questions below. All analysis must be completed using your own GSS data set. Failure to use your own GSS data set will result in a zero for the question. As above, you will need to read and interpret the question to determine which statistical test is appropriate, as well as whether it is a one-tailed or two-tailed test. Similar to the questions above, you must: 1. State the null and research hypotheses 2. Provide the Z(critical), T(critical), or χ2 (critical) score corresponding to the α thresh- old for your test 3. Explicitly provide your test statistic that is in your SPSS output (the exception is for tests of proportion, as the test statistic is not returned by SPSS) 4. Provide your decision about statistical significance You should also substantively interpretthe results of your test (again, keep it short). All of the necessary SPSS output must be pasted into your document. 3. Is educational attainment independent from gender in the GSS? To answer this question, first start by recoding the variable EDUC into a new variable with categories for respondents who have completed the 12th grade or less, and respondents who have at least some college or more education. You will also need to use the variable SEX. Can you conclude that the two variables are independent at 99.9% level of confidence (10 points)
1)
Ho:X =
Ha:X
2)
Z CRITICAL VALUE IS 2.58 FOR TWO TAIL TEST
T CRITICAL VALUE IS 2.58 FOR TWO TAIL TEST
t-test = (sample mean - population mean)/ standard error
= (39.75-40)/0.518
= -0.481695568
so accept the null hypothesis because of calculated t value is less than critical t (2.58) value so, there is no significant evidence that sample mean and population mean are different .
confidence interval = mean t * se
= 39.75 2.58 * 0.519
= 39.75 1.33902
lower = 38.41098 to upper = 41.08902

Open the "Lab Dataset"
(HSCI390.sav) you have been using for lab assignments in SPSS. Your
analysis will focus on the variables "Gender" (Gender) and "Blood
Alcohol Content at last drinking episode" (BAC).
Researchers are interested in examining if the mean Blood
Alcohol Content at last drinking episode differs between men and
women. To examine their research question of interest, they will
use data from the sample of CSUN students contained in the
HSCI390.sav dataset.
Using SPSS for the analysis, you...
Part II: SPSS Application These questions require the use of SPSS. Remember you must submit all of your work within this word document. You will need to take a screen shot of your data view if necessary, or copy and paste your output into the spaces below. Remember to report the exact p value provided by SPSS output – simply reporting p<.05 or p>.05 is not acceptable (unless SPSS output states p=.000 – in that case you can report p<.001)....
You will be using your Framingham dataset to answer the following questions. You will be performing hypothesis testing. For each question, please write out the null hypothesis, alternate hypothesis, which test statistic you will be using (based on variable type). Then report the results from performing the analysis using SPSS. Make sure to report the test statistic, significance level, and whether you will accept or reject the null hypothesis and why. Finally, if you find significant differences, report the proper....

Please: You may NOT use Excel, SPSS, or any other statistical software to get your answers. You must show all of your by-hand computations for full credit. assume you’re using an alpha of .05, and a two-tailed test, to make your decision about whether to reject the null hypothesis.

Psy 248: STATISTICS- MARIA MIRANDA Computer Lab Assignment II, SP 2019 Comparing means using t-tests This assignment will give you practice choosing the appropriate test statistic to use for different research designs that all involve comparing using t-tests. You will need to enter the data, use SPSS to test hypothesis, and write a conclusion for each problem stating weather or not the samples differed significantly. To run all 3 tests, use: ANALYZE, COMPARE MEANS, and then select the type of...
