Answer:
Null hypothesis:
Alternative hypothesis:
And for this case we assume that we have equal variances so that means:
For this case the degrees of freedom are given by:
And replacing we got:
And the best answer would be:
a. 38
Step-by-step explanation:
For this problem we want to test the following:
Null hypothesis:
Alternative hypothesis:
And for this case we assume that we have equal variances so that means:
For this case the degrees of freedom are given by:
And replacing we got:
And the best answer would be:

You will have to cross multiply and also distribute the fractions like this:
2/3 of 3/8 times 16
so 3/8 times 16 is 6
Now take 2/3 of 6 and youll end up with 4! :)
Answer:
x=4.2/5.6
or
x=0.75 which is simplified
Ill try to assist you with these
<span>x-y * x+y = x^2 -y^2
now how about x^4+64 = x^2 -4x+8 * x^2 +4x+8</span>
