Thank you for using the site. How may I help you?
Ok. I'll need a few minutes to read through this. I'll get back to you shortly.
This is a bit like coming in at the middle of a conversation, so I'm trying to catch up with what may have already been done here.
Do you have all this information in a Word document, or even a PDF? Tables of information don't show up well when they are copied and pasted, so it might be helpful to have the original document. If you have one, could you attach that document to your reply? If not, we'll manage.
Where did all of this analysis data come from? Was this supplied to you as part of the project?
Do you know what software application was used?
Ok, it may not be necessary to attach the Word document.
(I have more to say, but it disappeared and I'll need to retype it. Hang on just a sec...)
The way that I see it, none of the tables of statistical information (other than the raw data) will help to address the research question that is being asked, which is "Do native English speakers take longer to state the colors compared with the nonnative speakers?"
Each of the tables given seems to compare pairs of variables other than "NECW vs SSCW".
The test statistic of 4.72652616 and the critical t-value of 1.734063592, and the resulting conclusion, are correct, but they are not supported by any of the other information that was included.
I can write up a formal hypothesis test that addresses the research question, but it won't be using any of the information provided other than the table of raw data.
Will that meet your needs for this project?
Ok, I'll get that written up and posted for you as quickly as I can.
Given the sizes of the samples, we don't have any choice but to use a t-test.
Here is the completed hypothesis test:
