Expert Solution

Step 1

Provided information is, according to an article natural ratio of girls to boys is 100:105. Randomly 150 births are chosen, there are 65 girls and 86 boys.

It is claimed that girls born in china are 46.7%

Hypotheses can be constructed as:

H₀: p=0.467

H₁: p≠0.467

x=64, n=150, p=x/n= 0.4267

The random variable p represents the sample proportion of the girls in the china.
