Construct a confidence interval of the population proportion at the given level of confidence. x = 125, n = 250, 90 % confidence
madam [21]

Answer: 90% confidence interval would be (0.448, 0.552).

Step-by-step explanation:

Since we have given that

x = 125

n = 250

So, \hat{p}=\dfrac{x}{n}=\dfrac{125}{250}=0.5

We need to find the 90% confidence interval.

so, z = 1.64

So, interval would be

\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.5\pm 1.64\sqrt{\dfrac{0.5\times 0.5}{250}}\\\\=0.5\pm 0.0519\\\\=(0.5-0.0519,0.5+0.0519)\\\\=(0.448,0.552)

Hence, 90% confidence interval would be (0.448, 0.552)

Apply the properties of integer exponents to identify all of the expressions equivalent to 1/8.
Alborosie

Answer:

The answers are A , C , D

Step-by-step explanation:

Lets revise the rule of exponent

* a^{n}*a^{m}=a^{m+n}

* \frac{a^{m}}{a^{n}}=a^{m-n}

* \frac{1}{a^{-m}}=a^{m}

* (\frac{a}{b})^{-m}=(\frac{b}{b})^{m}

Now lets solve the problem

We need all the expressions equivalent to \frac{1}{8}

A.

∵ 2^{-3}=\frac{1}{2^{3}}

∵ 2³ = 8

∴ 2^{-3}=\frac{1}{8}

Answer A is equivalent to \frac{1}{8}

B.

∵ 2³ = 8

Answer B is not equivalent to \frac{1}{8}

C.

∵ 2³ = 8

∴ \frac{1}{2^{3}}=\frac{1}{8}

Answer C is equivalent to \frac{1}{8}

D.

∵ 2^{2}*2^{-5}=2^{2+-5}=2^{-3}

∵ 2^{-3}=\frac{1}{2^{3}}=\frac{1}{8}

Answer D is equivalent to \frac{1}{8}

E.

∵ 2^{-2}*2^{5}=2^{-2+5}=2^{3}

∵ 2³ = 8

Answer E is not equivalent to \frac{1}{8}

<em>The answers are A , C , D</em>
