In the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births
during Jan 2018 to Jan 2019 and found 400 twins in total. Which of the following are true?a. The proportion of twin births during Jan 2018 to Jan 2019 is 03. b. The proportion of twin births during Jan 2018 to Jan 2019 is.04 c. The probability of twin births among the general population is 03. d. The probability of twin births among the general population is .04 e. Príobserving a sample proportion of twin births from a random sample of 10,000 ive births < 0.04) -0.03. f. Priobserving a sample proportion of twin births from a random sample of 10,000 live births 0.04) 0.5. g. Probserving a sample proportion of twin births from a random sample h. PrObserving a sample proportion of twin births from a random sample of 10,000 live births <. 0.03)-05. of 10,000 live births 0.03)-0.04
Given that in the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births during Jan 2018 to Jan 2019 and found 400 twins in total.
From the above we find that population proportion is 0.03 and observed sample proportion is 0.04
Well first I would subtract 7 because the seven books aren’t in the cartons, which will give you 120. Then you divide by 10 to get 12, the amount of cartons
