The only significance levels I know of are 0.010 and 0.05.. A?

or how do you solve for the levels?!

Test Statistic:
t = (xbar-mu)/(s/sqrt(n))
t = (13.88-14)/(0.24/sqrt(16))
t = -2

n = 16 or 14?

there are 16 items in the sample, so n = 16

ic ic ok..

SO... A!

Then I'm confused.. :(

you reject H0 if alpha = 0.05 or alpha = 0.10

Ic so A is false then. I'm not sure what Wolfram is exactly showing us....?

it's showing the p value

Ic hmm...

So how do we test the other levels?

Damn I'm in trouble... 4 Q's in 30 mins..... :(

"test the other levels"?

The Sig levels, for B, C and D?

Oh, so B?

but not at 0.025 since 0.03197 is not less than 0.025, so the answer is B

yeah
