@jim_thompson5910 please help!!

show me what you have so far

*since every participant has to take BOTH tests

yes they do

Oh I see. You're saying the group of 11 takes the ARSMA first, nvm

yes

so yeah that sounds like a good idea to split up the groups

okay, i need help with parts B and C

what are the two hypothesis?

yeah or you can say
Ho: mu1 = mu2
Ha: mu1 =/= mu2

mu1 = mu2 is the same as mu1 - mu2 = 0

okay! gotcha!

ohh okay i see what youre saying

strange how alpha isn't given. I'm going to assume it's 0.05

okay! sounds good! okay so this is what i would put in my calc?
u0: ?
xbar: 0.2519
Sx:0.2767
n:22

you went to a t-test right?

yes

basically the null hypothesis is that the difference is 0

so that is why mu0 is 0

wait in the calculator what would we put in for u0?

xbar = 0.2519
s = 0.2767
n = 22

0 for mu0

oh okay

im getting t=4.270024322
p=3.4065864E-4

3.4065864E-4 is the same as saying 3.4065864 * 10^(-4) = 0.00034065864

this p value is very small

what does a very small p value tell us?

that we reject the Ho

correct on both

is that it for b?

yeah

that wraps up the hypothesis test

okay what about for C

i am getting (.12922, .37458)

for me, the data values typed in from the T-test should pop up for the T interval too

me too

yes my calc did the same

Question: is 0 in that interval?

okay thank you so much! youre the best :)

no

okay thank you again!!
