Domain is the x-values
Range is the y-values
Both listed in order from least to greatest
<u>The reflection of any point across the x-axis</u>:
⇒ means that x-coordinate remains the same
⇒ <em>but</em> the y-coordinate is <em>multiplied by '-1'</em>
<em />
<u>In this case</u>:
⇒ (50,25) <em>becomes</em> (50,-25)
<u>Answer: (50,-25)</u>
<u></u>

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>.
