Answer:
a = 0.05
Claim: The success rate of the XSORT method of gender selection.
x = 55
n = 100
Null and alternative hypothesis is
H0:P=0.5 Vs P 0.5
p0 : 0.5
x : 55
n : 100
prop : p0
calculate
we get
z = 1
p = 0.317310
so p value > 0.05 we fail to reject null hypothesis.
Conclusion : There is sufficient evidence that we support null hypothesis.
That is the success rate of the XSORT method of gender selection

Answer:
Equation of the Ellipse
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the equation
x² + 2 x + 2y² - 12 y +11 = 0
⇒ x² + 2 x + 1 - 1 + 2(y² - 6 y )+ 11 = 0
x² + 2 x + 1 - 1 + 2(y² - 2(3) y+9-9 )+ 11 = 0
⇒ x² + 2 x + 1 - 1 + 2(y² - 2(3 y ) + 3²- 3² ) + 11 = 0
By using (a +b)² = a² + 2 a b + b²
(a -b)² = a² - 2 a b + b²
<u><em>Step(ii):-</em></u>
x² + 2 x + 1 - 1 + 2(y² - 2(3 y ) + 3²- 3² ) + 11 = 0
⇒ ( x+1)² +2( y-3 )² - 1 - 2(9) +11 =0
⇒ ( x+1)² +2( y-3 )² - 8 =0
( x+1)² +2( y-3 )² = 8
Dividing '8' on both sides , we get
This equation represents the Ellipse
