Geometric sequence

common ratio

1/8 (or 0.125)

Step-by-step explanation:

To get to the next number we have the mulitply the one before by 1/8

Because we are multiplying each time it's a geometric sequence

Because it's a geometric sequence we have a common ratio

I wrote before that to get to the next number we have to multiply it by 1/8 so that's the common ratio

ElenaW [278]

Answer: The margin of error = $3\%$

Step-by-step explanation:

Given

Sample size (n) = 1000

Population proportion = 0.4

$\alpha$ = 1 - confidence level

= 1 - 0.95

= 0.05

$margin\; of\; error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{p}}{(1 -\widehat{p})}}{n}}$

$margin\; of\; error = z_{\frac{0.05 }{2}\sqrt{\frac{{(0.4)}{(1 -0.4)}}{1000}}$

$= z_{0.025}\sqrt{\frac{{(0.4)}{(0.6)}}{1000}}$

$= 1.96\sqrt{\frac{{(0.4)}{(0.6)}}{1000}}$

= 0.03

The margin of error change to $2.5\%$ to $3\%$
