Answer:
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds are dependent of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.
The confidence interval is likely to contain the true value of the population parameter.
In this question:
Sample mean: 48%
Margin of error: 4%
48 - 4 = 44%
48 + 4 = 52%
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Answer:
the answe for that question is a
Answer:
its about 2
Step-by-step explanation:
Simplifying
7(3x + 5y) = 0
(3x * 7 + 5y * 7) = 0
(21x + 35y) = 0
Solving
21x + 35y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-35y' to each side of the equation.
21x + 35y + -35y = 0 + -35y
Combine like terms: 35y + -35y = 0
21x + 0 = 0 + -35y
21x = 0 + -35y
Remove the zero:
21x = -35y
Divide each side by '21'.
x = -1.666666667y
Simplifying
x = -1.666666667y
