Answer 1

what are your thoughts?

Answer 2

what is the probability of the rejection region for the claim?

Answer 3

It seems there would be a difference in the means.

Answer 4

your resoning? and then ill determine if i agree or not

Answer 5

Nevermind I think it would be answer b or d.

Answer 6

@amistre64

Answer 7

you agree that if the Pvalue of the test statistic is less than or equal to the Pvalue of the rejection region ... that we should reject?

Answer 8

if we are within 2sd 0, then we fail to reject otherwise we reject

-2(10) to 2(10) is our 'acceptance' region

22 is not within that region is it?

Answer 9

no

Answer 10

then we reject the hypothesis of 'no difference'

Answer 11

there appears to be a differnce if we reject that there is no difference :)

Answer 12

Doesn't a null hypothesis mean there is no difference?

Answer 13

Do you not agree that it would be b or d? @amistre64

Answer 14

null is that there is not difference

we reject the null and 'accept' the alternative ... ther IS a differnece

Answer 15

i dont know what this b or d stuff is, you have numbered options

1 There appears to be a difference between the means of the two populations.
the IS a diff

2 There appears to be no difference between the means of the two populations.
we rejected this

3 There appears to be a difference of 0 between the means of the two samples.
a diff of 0 is still 'no diff' that was rejected

4 There appears to be no difference between the means of the two samples
no diff, is still rejected

Answer 16

since we are asking about pop means, 3 and 4 are simply not relevant since they talk of samples

Answer 17

sorry by b and d I meant 2 and 4. lol
Thanks.

Answer 18

:) yep
