Answer:
Null hypothesis: <em>μ₁</em> = <em>μ₂</em>.
Alternate hypothesis: <em>μ₁</em> > <em>μ₂</em>.
Step-by-step explanation:
The experimenter want to see whether laboratory rats would, on average, eat more when confined to a crowded cage or an uncrowded one.
(1)
The null hypothesis for this test is defined as:
<em>H</em>₀: The rats would, on average, not eat more when confined to a crowded cage or an uncrowded one, i.e. <em>μ₁</em> = <em>μ₂</em>.
(2)
The alternate hypothesis will be directional. This is because the experimenter wants to determine whether the rats eat more or not.
So the alternate hypothesis is:
<em>H</em>ₐ: The rats would, on average, eat more when confined to a crowded cage or an uncrowded one, i.e. <em>μ₁</em> > <em>μ₂</em>.

Step-by-step explanation:
<h3>55/z + 1/5 = 7/z</h3><h3>>1/5=7/z -55/z</h3><h3>>1/5= -48/z[do cross multiplication]</h3><h3>>1*z=5*-48</h3><h3>>z=-240</h3><h3>this is ur answerr..hope it helped u^_^</h3>
This sequence is not a geometric.
It is because, common ratio = 6/3 = 2
9/6 = 1.5
As the ratio's are not same, it is not a G.P
Hope this helps!
Answer: 8.
Step-by-step explanation:
Simplify the equation by getting rid of the exponents.
Which is then simplified to:
, or 64/8. Divide to get your answer.
It's just the value of itself
so it's 5.23
