A college student organization wants to start a nightclub for students under the age of 21. To assess support for this proposal,

eduard

Answer:

a) Sample size = 822

b) Margin of error = 0.03407

Step-by-step explanation:

We are given the following in the question:

p = 74% = 0.74

a) Sample size is required to obtain margin of error of 0.03

Formula:

$\text{Margin of error} = z_{\text{statistic}}\times \sqrt{\dfrac{p(1-p)}{n}}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.03 = 1.96\times \sqrt{\dfrac{0.74(1-0.74)}{n}}\\\\n = (\dfrac{1.96}{0.03})^2(0.74)(1-0.74)\\\\n = 821.24 \approx 822$

Thus, the sample size must be approximately 822 to obtain a 95% confidence interval with an approximate margin of error of 0.03

b) Margin of error for the 95% confidence interval

p = 54% = 0.54

Formula:

$\text{Margin of error} = z_{\text{statistic}}\times \sqrt{\dfrac{p(1-p)}{n}}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$\text{Margin of error} = 1.96\times \sqrt{\dfrac{0.54(1-0.54)}{822}}\\\\=0.03407$

The margin of error now will be 0.03407.

What are the solutions to the equation?

viva [34]

$\qquad\qquad\huge\underline{{\sf Answer}}♪$

Let's solve ~

$\qquad \sf \dashrightarrow \:f(x) = g(x)$

$\qquad \sf \dashrightarrow \:x + 2 = - {x}^{2} + 4$

$\qquad \sf \dashrightarrow \: {x}^{2} + x + 2 - 4 = 0$

$\qquad \sf \dashrightarrow \: {x}^{2} + x - 2 = 0$

$\qquad \sf \dashrightarrow \: {x}^{2} + 2x - x - 2 = 0$

$\qquad \sf \dashrightarrow \:x(x + 2) - (x + 2) = 0$

$\qquad \sf \dashrightarrow \:(x + 2)(x - 1) = 0$

Hence, x = -2 or x = 1
