<h2>Answers:</h2>

2x^2+8x+3
(x-12)(X+2)
x-3

Solution,

3x^2+5x-6+(-x^2+3x+9)

 = 3x^2+5x-6-x^2+3x+9

 = 3x^2-x^2+5x+3x-6+9

 =2x^2+8x+3

 2. x^2-10x-24

 = x^2-(12-2)x-24

 = x^2-12x+2x-24

 = x(x-12)+2(x-12)

 =(x-12)(X+2)

3. 3x^2-9x

 take the common,

 = 3x(x-3)

JulsSmile [24]

Answer:

a) test statistic = 2.12

b) p-value = 0.017

c) we reject the Null hypothesis

Step-by-step explanation:

Given data :

N = 200

girls (x) = 115 , Boys = 85

p = x / n = 115 / 200 = 0.575

significance level ( ∝ ) = 0.1

aim : test whether the proportion of girls births after the treatment is greater than 50% that occurs without any treatment .

A) Determine the test statistic

H0 : p = 0.5

Ha : p > 0.5

to determine the test statistic we will apply the z distribution at ( ∝ ) = 0.1

Z - test statistic = ( 0.575 - 0.5) / $\sqrt{0.5*0.5 / 200}$ = 2.12

b) determine the p-value

The P-value can be determined using the normal standard table

P-value = 1 - p(Z< 2.12 ) = 1 - 0.9830 = 0.017

c) Given that the p value ( 0.017 ) < significance level ( 0.1 )

we will reject the H0 because there is evidence showing that proportion of girls birth is > 50%
