According to an article in newsweek, the natural ratio of girls to boys is 100: 105. in china, the birth ratio is 100: 114 (46.7% girls). suppose you don’t believe the reported figures of the percent of girls born in china. you conduct a study. in this study, you count the number of girls and boys born in 150 randomly chosen recent births. there are 60 girls and 90 boys born of the 150. based on your study, do you believe that the percent of girls born in china is 46.7?

No, I don't believe that percent of girls born in china is 46.7.

Step-by-step explanation:

Given

Natural ratio of girls to boy =100:105

In China , the birth ratio = 100:114

Number of girls=46.7%

In our study

Number of girls=60

Number of boys= 90

Total number of birth =150

To find the percentage of girls in our study

Percentage of girls=40%

Therefore, the percentage of girls in our study is 40% not 46.7%

Hence, I don't believe that percentage of girls born in China is 46.7%.
