We wish to determine if infants whose parents are both native to China, but whose children were born in the United States, have lower birth weights than other children
born in the United States. We randomly selected 493 infants whose parents were native
to China, but were born in the USA. They had a mean weight of 3,195 g. Find the
probability that infants whose parents are both from China have a lower birth weight
than other infants born in America. Is this usual?|

The value of the second number is 43

Step-by-step explanation:

2x+4=86

2x=82

x=41

41+2=43

I hope you find this helpful :))
