Answer:
Step-by-step explanation:
We just multiply the values on the edges like we are finding the area of a square, L * L = area.
4x * 5x = 20x^2
4x * 8 = 32x
3 * 8 = 24
3 * 5x = 15x
Next add the answers together
20x^2 + 47x + 24
Answer:
Z = -6.3
Step-by-step explanation:
Given that:
Since the alternative hypothesis is less than 0.28, then this is a left-tailed hypothesis.
Sample sixe n = 800
= 0.217
The standard error
Since this is a single proportional test, the test statistics can be computed as:
Z = -6.3
Its either A or D if its wrong sorry hope this helped tho
