(a) Find t. (Give your answer correct to two decimal places.)

Correct: Your answer is correct.0.52 .

(ii) Find the p-value. (Give your answer correct to four decimal places.)

0.6036 I can not figure out how to find p value it always comes out wrong

Anyone know a simple way to determine the p-values, I keep missing them. If I see example I usually can figure it out but did not work this time. I have TI83 Calculator but can not figure out how to use it. So not sure if I can get it on it or not.

Different

xbar = -1.2

s = 5.17

n= 5

t = -1.2/(5.17/sqrt(5))

t = -0.52

p-value = 0.6310

To get p-value

Stat oldest L1, youngest L2

difference between oldest and youngest L3 after quit and stat tests then T-test data

List: L3

**Tracy**, Wednesday, June 26, 2013 at 12:39amwhat do you mean with stat oldest L1, etc. Have a question I have a TI-83 Plus calculator, is there a way of putting in the information to get the p value or do you still have to look at a chart.

When I read the instructions on it, it mentioned finding the z value to get to the p value, I am confused I am so sorry.
