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
