Answer:
+1.12 and -1.12
Step-by-step explanation:
Let the two z scores be
.
Since the two Z-scores that separate the middle 73.72% on the Standard Normal Curve, this can be represented by the equation:

From the z table of the normal distribution, z₁ = 1.12. That is a z score of 1.12 gives 0.8686.
The two z scores are +1.12 and -1.12 = ± 1.12
Step-by-step explanation:

Step-by-step explanation:
For
: (0,3) (2,2)
The equation is in slope intercept form. y=mx+b
The y intercept is 3.
The slope is 1/2.
Moving one unit down and 2 units to the right, we get (2,2)
For
: (0,-2) (1,0)
The y intercept is -2.
The slope is 2.
Moving 2 units up and 1 unit to the right, we get (1,0)
