7.1.13 Question Help Use the sample data and confidence level given below to complete parts (a) through (d). A research institut

r-ruslan [8.4K]

Answer:

The Point estimate of the Population proportion E = 0.039≅0.04

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 992

and x = 570

The Population proportion

$p = \frac{x}{n} = \frac{570}{992} = 0.5745$

Step(ii):-

The point estimate of the Population proportion is determined by

$E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }$

E = 0.039≅0.04

Final answer:-

The point estimate of the Population proportion E = 0.039≅0.04

Which set of numbers represents solutions of the inequality m>20?

zlopas [31]

Answer:

{21, 22, 23, 24}

Step-by-step explanation:

m>20 means that m is greater or more than 20, therefore 21, 22, 23, and 24 are all greater than 20 so that is the answer.

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29)

vichka [17]

Answer:

x=-4,1,2+5i,2-5i

Step-by-step explanation:

Given is an algebraic expression g(x) as product of two functions.

Hence solutions will be the combined solutions of two quadratic products

$g(x) = (x^2 + 3x - 4)(x^2 - 4x + 29)\\$

I expression can be factorised as

$(x+4)(x-1)$

Hence one set of solutions are

x=-4,1

Next quadratic we cannot factorize

and hence use formulae

$x=\frac{4+/-\sqrt{16-116} }{2} =2+5i, 2-5i$
