Null Hypothesis and T Test Questionnaire

Null Hypothesis and T Test Questionnaire

Description

1) T-TEST- The Lab 2 data set includes a measure of highest educational degree completed (DEGREE). Test whether there is a significant difference between those with less than high school (coded 0) and those with a bachelor’s degree (coded 3) in the number of hours they watch television (TVHOURS) and in the number of hours on the Internet per week (WWWHR). Assume ? is .05 for a two-tailed test. Prepare a statement to summarize your findings that includes both the 5 steps AND the information that would accompany the 5 steps you should use for the correct independent samples t- test. (hint: can you assume equal variances for both of these groups?) Be sure to use and include your output to support your statements.

2) CIs- Using the Lab 2 data set, you’ll need to calculate 99% confidence intervals for both these two variables (EDUC, PRESTG80) for each of the lower, working, middle, and upper classes (CLASS). Make a summary statement of your findings and use your output from each variable to support your statements. Just do the mean, lower and upper bound

EDUC (Respondent’s highest year of school completed)

PRESTG80 (Respondent’s occupational prestige)

3) CHI-SQUARE- Use the Lab 2 data set to test the relationship between SEX (male, female) and FECHLD (a working mother does not hurt her children). Create a bivariate table and ask for appropriate percentages and expected values. Have SPSS calculate chi-square for the table. Test the null hypothesis at the .05 significance level and include the both the 5 steps AND the information that would accompany the 5 steps you should use for the chi-square test. What do you conclude? Be sure to use and include your output to support your statements.
