Question

i need help questions 6,7,8

A study was conducted to compare four groups of Chemistry graduate students on satisfaction with graduate
life. The four groups consisted of students who 1) pay tuition and receive no stipend, 2) have tuition waiver but
receive no stipend, 3) have a tuition waiver and receive a university stipend, and 4) receive a university
fellowship as well as free health care. Higher scores on the Life Satisfaction Scale indicate greater satisfaction.
A total of 40 graduate students complete the scale.
Use the SPSS data file Project 5 data set to conduct a one-way ANOVA using SPSS to determine if there are
any differences in the mean satisfaction of students in these four groups. Assume an alpha of .05.
1. State H, statistically.
State HA statistically.
2. Report your degrees of freedom and your critical F-value. In other words, using your F-table what
critical value does your obtained F-value have to surpass in order for the samples to be significantly
different?
3. Use SPSS to run a one-way ANOVA and copy and paste the SPSS output.
4. What is k? What is ngotal? What is n per group?
5. What is s'bet? What is swthn?
6. State your obtained F from the SPSS output, the dfs, and your significance level (p-value).
7. State your decision regarding Họ. Why did you make this decision, statistically?
8. State your conclusions. What does this mean?
9. If you wanted to know specifically which means differed (i.e., if Group 1 differed from Group 2), what
type of statistical procedure would you need to follow up with?
