Question 9According to a Pew Research Center study, in May 2011, 33% of all American adults had asmart phone (one which the user can use to read email and surf the Internet). Acommunications professor at a university believes this percentage is higher among community college students. Sheselects 349 community college students at random and finds that 138 of them have a smart phone. In testing thehypotheses:Ho: p=0.33 versusHa: p > 0.33,she calculates the test statistic as z = 2.5990.Then the p-value =(Please round your answer to four decimal places.)

Each hypothesis test has two types of methods to make decisions. They are: P-value approach…

TOR is free and open-source web browser (https://www.torproject.org/) enabling anonymous communication. A researcher wanted to learn about how many College students have heard of the TOR web browser. She randomly selected 234 LaGuardia students and found that 21 have heard of the TOR web browser. She concluded that approximately 9% of LaGuardia students have heard of TOR.

USA Today (Feb. 17, 2011) described a survey of 1,008 American adults. One question on the survey asked people if they had ever sent a love letter using e-mail. Suppose that this survey used a random sample of adults and 205 stated that they had written a love letter using e-mail. Is this evidence that more than 20% of American adults have written a love letter using e-mail? Use a level of significance of 5%. a) p: (3 decimal places) b) Complete the following areas.

The book Survey Responses: An Evaluation of Their Validity, by E. J. Wentland and K. Smith (Academic Press), includes studies reporting the accuracy of answers to questions from surveys. A study by Locander and others considered the question “Are you a registered voter?” Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 93 people were asked the voter registration question face-to-face. Seventy-nine respondents gave accurate answers (as verified by city records). Another random sample of 83 people were asked the same question during a telephone interview. Seventy-four respondents gave accurate answers. Assume that the samples are representative of the general population. (a) Let p1 be the population proportion of all people who answer the voter-registration question accurately during a face-to-face interview. Let p2 be the population proportion of all people who…
When the 2000 GSS asked whether human beings developed from earlier species of animals, 53.8% of 1095 respondents answered that this was probably or definitely not true. Question: What is the null and alternative hypothesis for this question
A golf instructor wants to test the following claim: of all golf students in the United States, 65% need the most help with short game shots, 22% need the most help with approach and swing, 9% need the most help with driver shots, and 4% need the most help with putting. A random sample of golf students finds that 276 need the most help with short-game shots, 99 need the most help with approach and swing, 42 need the most help with driver shots, and 18 need the most help with putting. Test the claim at σ = 0.10.
The drug Finasteride is marketed as Propecia to help protect against male pattern baldness, and it also may protect against prostate cancer. A large sampleof healthy men over age 55 were randomly assigned to receive either a daily Finasteride pill or a placebo. The study lasted seven years and the men had annual check-ups and a biopsy at the end of the study. Prostate cancer was found in 804 of 4368 men taking Finasteride and in 1145 of the 4692 men taking a placebo. 1.) Assume that the true risk of developing prostate cancer for a man taking Finasteride is equal to the one in this sample. If 10 men from the Finasteride group are randomly selected, what is the probability that at least one of them will develop prostate cancer? Answer choices: a. 0.184 b. 0.816 c. 0.869 d. 0.131
People who experience online harassment either ignore it or respond via postings or involving authorities. Is one method more effective than the other? A 2014 Pew Research Center report, based on a random sample of American adults, found that 412 of the 549 respondents who had chosen to ignore online harassment thought that it was an effective way to deal with the issue. Of the 368 respondents who had chosen to respond to online harassment, 305 thought that it had been effective.
The article "Freedom of What?" (Associated Press, February 1, 2005) described a study in which high school students and high school teachers were asked whether they agreed with the following statement: "Students should be allowed to report controversial issues in their student newspapers without the approval of school authorities." Researchers hypothesized that the long-run proportion of high school teachers who would agree with the statement would differ from the long-run proportion of high school students who would agree. 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.

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and the National Institutes of Health (NIH), 42% of college students nationwide engage in “binge drinking” behavior, having 5 or more drinks in one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college that binge drink is actually different than the national proportion. In a commissioned study, 364 students are selected randomly from a list of all students enrolled at the college. Of these, 136 admitted to having engaged in binge drinking. The same college president is more interested in testing her suspicion that the proportion of students at her college that binge drink is different than the national proportion of .37. Use the statistic provided for her college above for your test. A. Define the null and alternative hypotheses to test this claim. B. By hand, calculate the test statistic for this test. C. Use…
In June 2015, Gallup conducted a poll of a random sample of 14,683 adults to determine the well-being of people living in the United States. One question asked, "Did you exercise at least 30 minutes for 3 or more days in the past week?" In the survey, 58.9% of males and 52.7% of females responded yes to this question. Which of the following is true about this scenario? A. O 58.9% and 52.7% are both parameters. B. O 58.9% and 52.7% are both statistics. C. If we took another random sample of 14,683 adults, we would expect to get the exact same results.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
