In China, the birth ratio is claimed to be 100 girls to 114 boys (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 64 girls and 86 boys born of the 150. Based on your study, do you believe that the percent of girls born in China is 46.7%? Conduct a hypothesis test at the 5% significance level. Part (a) State the null hypothesis. H0:  p ≥ 0.467 H0:  p = 0.467     H0:  p ≤ 0.467 H0:  p ≠ 0.467 Part (b) State the alternative hypothesis. Ha:  p < 0.467 Ha:  p > 0.467     Ha:  p ≠ 0.467 Ha:  p = 0.467 Part (c) In words, state what your random variable P' represents. P' represents the percent of boys born in China.P' represents the percent of girls born in China.    P' represents the number of girls born in China.P' represents the ratio of girls to boys in China.

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%).   In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 37% with a margin of error of 2.5%. Describe the conclusion about p using an absolute value inequality.   . That lets you type in a vertical bar | to represent absolute values. Also, when you type in  <  and then =, the symbolic entry option will automatically convert that to  ≤ . In the same way, if you type in  >  and then =, the symbolic entry option will automatically convert that to  ≥.   Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).

What is the relationship between the average income and the level of education in a given population, and how does this relationship vary across different regions and demographic groups?

For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 44% with a margin of error of 2.2%. Describe the conclusion about p using an absolute value inequality. The answer field below uses the symbolic entry option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in and then =, the symbolic entry option will automatically convert that to >.

A research company surveyed 1024 people who routinely fly for business travel purposes and found that 384 of them were generally satisfied with the flights they took. Find the standard error for the sample proportion of people who routinely fly for business travel purposes and are generally satisfied with the flights they take. Enter your answer as a decimal rounded to three decimal places.

Use the following information to answer the question. Many couples believe that it is getting too expensive to host an "average" wedding in the United States. According to the website www.costofwedding.com,theaveragecostofaweddingintheU.S.in 2009 was $24,066. Recently, in a random sample of 40 weddings in the U.S. it was found that the average cost of a wedding was $23,224, with a standard deviation of $2,903. On the basis of this, a 9 5% confidence interval for the mean cost of weddings in the U.S. is $22,296 to $24,152. Does the confidence interval provide evidence that the mean cost of a wedding has decreased? Explain your reasoning.
