In the first part of this question, we're going to be looking at the value of s.
00:05
The value of s is equal to the square root of s squared.
00:09
And for us to determine this s squared, our s squared is actually the ratio between our s s s, e, 2 and minus 2.
00:19
So making the substitutions, we are looking at a 1 -27 .3 divided by n minus 2, which is equal to 3.
00:28
So this gives us an s value that is equal to a square root of 4 .2 .4 -3.
00:37
This gives us an s value of 6 .51 for then moving on to the next part.
00:46
Now for the last part, which is part c and part b, what we need to do, recall that for us to determine if we should accept or reject null hypothesis, we need to determine a p value, which we then compare against a c.
01:01
Significance level.
01:02
So the difference between the p value and the significance level is what is then going to help us determine if we should accept or reject final hypothesis...
