The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

Answer: 14/11
Step-by-step explanation:
When 14/11 is multiplied by 1/4, you get a repeating decimal. All repeating decimals are rational.

The first step is to set one equation equal to x or equal to y.
Ex. y = ..... or x = .....
The next step is to substitute that equation into the second equation in place of the x (or y), whichever you set it equal to.
Ex. x + y = 3
2x + y = -1
y = -x + 3 2x + (-x + 3) = -1
x + 3 = -1
x = -4
y = -(-4) + 3 y = 7 (-4,7)
Answer:
y - 5 = 6(x - 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 6 and (a, b) = (2, 5), thus
y - 5 = 6(x - 2)
