Alik [6]

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>.

puteri [66]

Answer:

Equation: y = -3x -2

Graph: Attached below ↓↓↓↓↓

Step-by-step explanation:

The equation is y = -3x + b

We need B at this point.

Since we have a point given to us,( -2, 4)we can input the x and y

Solve:

4 = -3(-2) + b

4 = 6 + b

b = -2

So the equation we have is y = -3x -2

Let's graph the line.

We go 2 units below the x-axis, because the y-intercept is -2, and the slope is -3, so we go down 3 units, and to the right 1.
