EspañolAccording to previous studies, 10% of the U.S. population is left-handed. Not knowing this, a high school student claims that the percentage of left-handedpeople in the U.S. is 12%.The student is going to take a random sample of 900 people in the U.S. to try to gather evidence to support the claim. Let p be the proportion of left-handedpeople in the sample.Answer the following. (If necessary, consult a list of formulas.)(a) Find the mean of p.0.12(b) Find the standard deviation of p.X5(c) Compute an approximation for P(p≤0.12), which is the probability that there will be 12% or fewer left-handedpeople in the sample. Round your answer to four decimal places.A 27

A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.
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 39% with a margin of error of 1.3%. 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 ≤ . 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%).

According to an article in Newsweek, the natural ratio of girls to boys is 100:108. In Turkey, the birth ratio is 100: 118 (45.8% girls). Suppose you do not believe the reported figures of the percent of girls born in Turkey. You conduct a study. In this study, you count the number of girls and boys born in 140 randomly chosen recent births. There are 50 girls and 90 boys born of the 140. Based on your study, do you believe that the percent of girls born in Turkey is 45.8?
Suppose a community college has 10,000 students (the population). We are interested in the average amount of money a part-time student spends on books in the fall term. Asking all 10,000 students is almost an impossible task. A sample is taken using a list of students who take photography classes, and each of these students is surveyed. Do you think that this sample is representative of the entire 10,000 student population? Why or why not?
