The article "Freedom of What?" (Associated Press, February 1, 2005) described a study in which high school students and high schoolteachers were asked whether they agreed with the following statement: "Students should be allowed to report controversial issues intheir student newspapers without the approval of school authorities." Researchers hypothesized that the long-run proportion of highschool teachers who would agree with the statement would differ from the long-run proportion of high school students who wouldagree. Two random samples - 8,000 high school teachers and 10,000 high school students were selected from high schools in the U.S.It was reported that 39% of the teachers surveyed and 58% of the students surveyed agreed with the statement.A simulated null distribution of 1,000 differences in proportions created by using the Two Proportion applet is shown below.Total shuffles - 1000251Number of shuffles20Mean -0.000SD-0.007LUL0.024-0.026 -0,016 -0.006 0.004 0.014Shuffled diff in proportionsWhat is the strength of evidence against observed study results happening by chance alone?

QUESTION 3 In a random and independent sample of 4000 students 35% of them were in favor of more online courses. What is the multiplier for the 90% confidence interval level?
We survey 1004 teens age 13-19, we record whether or not they have had sex education. 817 respond that they have had some form of sex education. (a) Construct a 99% confidence interval for teens who have not had sex education. (b) How many teens would we have to sample in order to cut the margin of error in half?
Officials from Pennsylvania Department of Transportation (PENNDOT) question how a sample of 120 hours can prove whether or not more cars pass through with machine collections over manual collection, that is, how the results from the sample reflect the population. In a detailed paragraph of at least six to seven sentences, based on your knowledge and understanding of the concepts of inferential statistics, random sampling, and tests of statistical significance, respond to PENNDOT. Ensure that you mention what inferential statistics is and why we use it, what random sampling is, and what statistical significance is and why we test for it. if we ponder the relationship between commute time and job satisfaction while driving back and forth to campus. Your instructor hypothesizes that people with a shorter commute time will have higher degrees of job satisfaction. Randomly sampling 600 Valley commuters, the instructor finds the following data listed in frequencies: Table 2: Commuters…

A dowser has correctly located water for a well 1 out of 2 times in Jones County. In Jones County, someone who is just guessing has a 40% chance of locating water for a well. Does this sample provide sufficient evidence that the dowser can locate water and is not just guessing?
1. If the chance for a student passing a class is 50%, then the chance for a student not passing the class can be greater than 50%? true or false 2. 1.30% is not a true probability? true or false 3. Power is 1 minus the probability of making a type I error? true or false 4.
