wow....my professor took 3 days to teach us this, and I swear that I just now understand it after watching this video. Thank you for the clear and step by step instructions. I would however, have liked to see the T-chart to be able to visualize finding the p-value better.

If I dont have a calculator to find the P value then what do I do. I got confused there on step 4. I'm not sure where is the area part is and how to look for it. Thank you.

Thank you!

lol I can't concentrate because she is so cute!
On the other hand, great teacher, really breaks it down.
..Now if she could just drop it likes it hot.. haha

How did you calculate the P-value ? which is 0.0017

what's the real reasoning behind rejecting the null hypothesis if the p-value is lower than the alpha value.
yardconnec1 3 months ago in playlist Statistics Review
@yardconnec1 Yes, if P is less than alpha, we reject. The reasoning behind it is because the alpha is our rejection amount. Anything within that rejection amount will be rejected. The P-value is our testing amount. So, if P is within (less than) alpha we will reject. If P is greater than alpha then part of the P is outside of the rejection amount and therefore in the non-rejection amount, so we fail to reject the null.

@sco40 We are rejecting the null, because this is a test (as all hypothesis tests are) of the null hypothesis. When I state the interpretation, it says as much. Try paying closer attention. :)
Oh, by the way, u is a letter...you is a pronoun.

i don't quite understand step 4, if 3.15 is greater than the value given in the chart shouldn't you just reject it instead of trying to find the rough p-value?

@hoogiechugie We could just reject, because we know that we have a large t-value. However, doing the p-value approach, gives us the probability of the test statistic. It gives us a specific amount of evidence against the null.
