Overview
1. Calculations grade-12.5/15-This is her correction under
Ist comment:
Part 1 - full group descriptives: 5/5. Part 2 - subgroup descriptives: 4.5/5. The half point off is because per the directions on the spreadsheet you pulled your paper from, you were supposed to be comparing those 34 and under to those 35 and older. You did the split between 29 and 30 instead. If you were in my 16-wk class I'd honestly make you redo it, but this class moves too fast. I'd suggest you just take the deduction. Part 3 - t-test: 2/5. Your pooled variance, t-value, and critical value are all incorrect. The conclusion you reached would have been correct based on the values you calculated so I gave you those points, but you'll need to re-evaluate after you fix the calculations and critical value.
2nd comment:
Mm, nm, critical value point is being returned. I *meant* for you to use a directional value, but I don't think I actually said so, and you cannot read my mind. 2. Please double the final paper to make sure everything corrpounds to all. Bellow is what he on first reference for correction
Those are good articles... the only thing you're missing is dois, which are not the same as urls to the pages they're found on. For the first one, for example, when I click on the link you provided, there's a link underneath the title of the article: https://doi.org/10.3390/su11061683 That's the doi link that you need in place of the urls you have.
