An investment website can tell what devices are used to access their site. The site managers wonder whether they should enhance

lbvjy [14]

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 = $\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.26\times (1-0.26)}{131}}=\sqrt{0.00146870229008}$

$=0.0383236518364\approx0.038$

Determine whether the sequence is arithmetic, geometric, or neither, and justify your response.

Kobotan [32]

9514 1404 393

Answer:

geometric

Step-by-step explanation:

The signs of the terms alternate, so it cannot be an arithmetic sequence.

The ratios of terms are ...

6/-3 = -12/6 = 24/-12 = -2

The terms have a constant ratio of -2, so the sequence is geometric.
