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>.
