Answer: a) Unimodal and symmetric

b) 0.26

c) 0.038

Step-by-step explanation:

Given: Sample size of investors (n)= 131

True proportion of smartphone users(p) =26%

a) Since sampling distribution for the sample proportion is approximately normal when n is larger.

Normal distribution is Unimodal and symmetric.

So correct option : Unimodal and symmetric

b) mean of this sampling distribution = p = 0.26

c) standard deviation of the samplingdistribution = $\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.26\times (1-0.26)}{131}}=\sqrt{0.00146870229008}$

$=0.0383236518364\approx0.038$

Divide a^24-a^18+a^12 by a^6<br> what is the quotation?

lana66690 [7]

I think you mean "what is the QUOTIENT?"

$\dfrac{a^{24} - a^{18} + a^{12}}{a^6} =$

$= \dfrac{a^{24}}{a^6} - \dfrac{a^{18}}{a^6} + \dfrac{a^{12}}{a^6}$

$= a^{24 - 6} - a^{18 - 6} + a^{12 - 6}$

$= a^{18} - a^{12} + a^{6}$
