(-4, 2), (-1, 2), and (-4, 0
Answer:
The probability that the sample proportion will be at least 3 percent more than the population proportion is 0.6157
Step-by-step explanation:
We need sample proportion between 0.75 - 0.03 = 0.72 and 0.75 +0.03 = 0.78. Here we have p = 0.75 and n= 158.
So z-score for sample proportion q = 0.72
z = = = - = - 0.872
So z-score for sample proportion q = 0.78
z= = = = 0.872
Therefore the probability that the sample proportion will be within 3 percent of the population proportion is
P( 0.72 < q < 0.78) = P ( -0.872 < z < 0.872)
= P( z < 0.872) - P( z < -0.872)
= 0.80785 - 0.19215
= 0.6157
Answer:
so looks like they want you to solve each of them first, then plot them on the number lines.
1) x+8 >= 18
subtract 8 from each side
x >= 10
so for this one you would plot the point (a closed circle, since it's greater than or equal to) on the ten, and draw an arrow pointing to the right
2) x-1 > 6
add 1 to each side
x > 7
for this one you would plot an open circle on the 7 and draw an arrow to the right
3) -7+x >= -8
add 7 to each side
x >= -1
for this one you would plot a closed circle on the -1 and draw an arrow to the right
4) x-1 <= 3
add 1 to each side
x <= 4
for this one you would plot a closed circle on the 4 and draw an arrow to the left
