Problem 10.6

We are interested in testing whether or not a coin is balanced based on the number of heads Y on 36 tosses of the coin. (H0 : p = .5 versus Ha : p = .5). If we use the rejection region |y 18| 4, what is a the value of ? b the value of if p = .7?

Chapter 8 Notes – Surveys and Sampling Poll: What proportion of all registered voters in the state support the Affordable Care Act Would 1000 voters in Iowa or 1000 voters in NY provide a more accurate estimate (answer in lecture) Example: What percent of St. Cloud teenagers have a smart phone  Unknowable so estimate it --- from a sample --- how to take the sample  Is the estimate accurate What is the Population of interest All teenagers (13 – 19 years old) in St. Cloud What is the Parameter of interest (answer in lecture) What is the Sample (answer in lecture) What is the Statistic of interest (answer in lecture) How to take the sample (some answers in lecture)  Suppose we go to the mall and interview teenagers. Why is that a bad idea 
