Considering the situation described, the scientist's null and alternative hypothesis are described by:
Null hypothesis 
; Alternative hypothesis 
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by 
is of 0, hence:
At the alternative hypothesis, it is tested if there is a difference, hence:

Answer:
half of 2 is 1, half of 3 is 1.5,half of 4 is 2.
Step-by-step explanation:
Answer: x=-3/4
Step-by-step explanation:
Since we know f(x)=6, we can set it equal to the equation.
6=9+4x [subtract 9 on both sides]
-3=4x [divide both sides by 4]
x=-3/4
V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in
V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3
120 is the answer im pretty sure
