Hi there, StudentInNeed:, and I know you're new to our forum, but I'd like to ask you to carefully read the
Forum Rules{click}, and follow them. You agreed to read and follow them when you signed up, and you're not really doing that.
You have many questions on the linked webpage, some abstract, some with multiple parts, some that you've done and some that just follow logically from what you've already done. That webpage mentions multiple trials, but you only mention one set of data points. That's not how things are done here.
Write down the first question you can't do, here, one forum, with your keyboard. Show us what you tried, either by re-reading your textbook, class notes, the lab writeup. And we'll see how we can help.
