Research question: Is there a discernible difference between students who worked 10 hours or fewer per week and those who worked 20 hours or more per week in terms of their grade point averages?

Null hypothesis:The grade point averages of students who worked 10 hours or fewer per week compared to those who worked 20 hours or more per week were not significantly different.

What does this independent sample t-test show:

1. explain the descriptive statistics of the charts which is used first to analyze the data and check the sample for outliers and normality
2. explain the sample size, sampling method, and measurement methods
3. list which of the two types of t-test (one-sample or dependent samples) would be used to test your null hypothesis and explain why that is the correct choice. This should include explaining the "assumptions" for using t-tests.
4. Report the descriptive statistics (means and standard deviations) and the inferential statistics (t-test results)
5. Explain whether or not you rejected the null hyothesis and why
6. Calculate Cohen's d statistic as your measure of effect size and report that value
7. Explain in a brief description of the results and what it means about the research question. Was there a difference between the means you looked at and what would that tell you about the primary research question? Interpret the effect size measures.
