One-child families ~ The one-child policy was introduced in China in 1979 by the Chinese government. This policy set a limit on the number of births each Chinese couple could have. A research group randomly chose 305 Chinese couples and found 160 of them with only one child. Among 448 American couples the group studied, 96 couples gave birth to only one child.
The research group wants to estimate the actual difference between the proportions of Chinese and American couples who have only one child.
Notation: 1=Chinese and 2=American.
Based on this data, what is the upper bound for a 95% confidence interval for the difference in the population proportions, p1-p2?
Here, , n1 = 305 , n2 = 448
p1cap = 0.5246 , p2cap = 0.2143
Standard Error, sigma(p1cap - p2cap),
SE = sqrt(p1cap * (1-p1cap)/n1 + p2cap * (1-p2cap)/n2)
SE = sqrt(0.5246 * (1-0.5246)/305 + 0.2143*(1-0.2143)/448)
SE = 0.0345
For 0.95 CI, z-value = 1.96
Confidence Interval,
CI = (p1cap - p2cap - z*SE, p1cap - p2cap + z*SE)
CI = (0.5246 - 0.2143 - 1.96*0.0345, 0.5246 - 0.2143 +
1.96*0.0345)
CI = (0.2427 , 0.3779)
upper bound = 0.3779

What is your idea about following paragraphs? There are many young people looking to start families. Whenever I log onto Facebook or Instagram, I see pictures being shared/posted of engagements and gender reveal parties. Sometimes I think about it and I get jealous, because I would like to start a family, but I am too consumed in my studies and work. Starting a family now would be selfish of me because I won't be able to devote my full attention...
