Given:
p = 20% = 0.2, sample proportion
n = 5000, sample size.
Confidence level = 95%
The confidence interval is
(p - 1.96k, p + 1.96k)
where
Therefore the 95% confidence interval is
(0.1943, 0.2057) = (19.4%, 20.6%)
Answer: The 95% confidence interval is (19.4%, 20.6%)
p = 20% = 0.2, sample proportion

Answer: The 95% confidence interval is (19.4%, 20.6%)
Answer:
1. 4 + 26x² + 4x - 48
2. 2 - 23x² + 60x - 32
3. + 7
- 4x + 2
+ 14x² - 8
4. 2 +
- 28
+ 3x + 12
Step-by-step explanation:
To multiply polynomials, simply distribute whatever's outside the largest set of parenthesis, then combine like terms.
1) Distribute the parenthesis (x + 6):
x(4x² + 2x - 8) + 6(4x² + 2x - 8)
4 + 2x² -8x + 6(4x² + 2x -8)
4 + 2x² -8x + 24x² + 12x - 48
Combine like terms:
4 + 26x² + 4x - 48
2) Distribute the parenthesis (x - 8):
x(2x² - 7x + 4) + (-8)(2x² - 7x + 4)
2 - 7x² + 4x + (-8)(2x² - 7x + 4)
2 - 7x² + 4x + -16x² + 56x - 32
Combine like terms:
2 - 23x² + 60x - 32
3) Distribute the parenthesis (x + 2):
x( + 7x² - 4) + 2(
+ 7x² - 4)
+ 7
- 4x + 2(
+ 7x² - 4)
+ 7
- 4x + 2
+ 14x² - 8
No like terms to combine, so:
+ 7
- 4x + 2
+ 14x² - 8
4) Distribute the parenthesis (x + 4):
x(2 - 7
+ 3) + 4(2
- 7
+ 3)
2 - 7
+ 3x + 4(2
- 7
+ 3)
2 - 7
+ 3x + 8
- 28
+ 12
Combine like terms:
2 +
- 28
+ 3x + 12
hope this helps!
