### Hypothesis Testing ExampleAccording to a Pew Research Center study, in May 2011, 33% of all American adults had a smartphone (one which the user can use to read email and surf the Internet). A communications professor at a university believes this percentage is lower among community college students. She selects 352 community college students at random and finds that 122 of them have a smartphone. In testing the hypotheses:- **Null Hypothesis (Ho):** $ p = 0.33 $- **Alternative Hypothesis (Ha):** $ p < 0.33 $### Steps for Hypothesis Testing1. **Significance Level:** Use a level of significance of $ \alpha = 0.05 $.2. **Data Analysis:** Use the unrounded values in Excel to find the answers for the specific calculations needed in questions #3 and #4 (details not provided).3. **Finding the p-value:** Perform the necessary calculations to determine the p-value.4. **Conclusion:** Decide whether to reject or fail to reject the null hypothesis based on the p-value and the level of significance.### Instructions for Excel- Utilize Excel for precise calculations by entering the data about smartphone ownership among the selected students.- Implement the formulas needed to find the p-value and determine the statistical significance of the results.### ConclusionThe communication professor will use the results to conclude whether there is enough evidence to support her belief that the proportion of community college students with smartphones is less than the national average reported by the Pew Research Center in 2011. The action (reject or fail to reject) depends on the calculated p-value compared to the significance level.

In a survey of working parents (both parents working), one of the questions asked was "Have you refused a job, promotion, or transfer because it would mean less time with your family?" 480 men and 480 women were asked this question. 21% of the men and 27% of the women responded "Yes". Based on this survey, can it be concluded that there is a difference in the proportion of men ( p1 ) and women ( p2 ) responding "Yes"? Use a significance level of α=0.1 for the test. Step 2 of 5 : Compute the weighted estimate of p, p‾. Round your answer to three decimal places.
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.

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.
In 2002 the Supreme Court ruled that schools could require random drug tests of students participating in competitive after-school activities such as athletics. Does drug testing reduce use of illegal drugs? A study compared two similar high schools in Oregon. Wahtonka High School tested athletes at random and Warrenton High School did not. In a confidential survey, 5 of 140 athletes at Wahtonka and 26 of 143 athletes at Warrenton said they were using drugs. Regard these athletes as SRSs from the populations of athletes at similar schools with and without drug testing. Wahtonka sample size: 142 Wahtonka drug users: 6 Warrenton sample size: 145 Warrenton drug users: 27(c) Give the plus four 96% confidence interval for the difference between the proportion of athletes using drugs at schools with and without testing. Interval:
In 2014, Scotland was considering independence from England, going so far as to take a referendum vote. One opinion poll taken at the time showed that 51% of Scots favored "independence." In another poll taken at that same time, only 34% favored being "separate" from England. The primary reason these results differed by so much is that a. samples will usually differ just by chance due to random sampling. b. the wording of questions has a big effect on poll results. c. more follow-up efforts reduced the nonresponse rate of the second poll. d. the sample sizes are different, so the margins of error are different.
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.
Many fundraisers ask for donations using email and text messages. A paper describes an experiment to investigate whether the proportion of people who make a donation when asked for a donation by email is different from the proportion of people who make a donation when asked for a donation in a text message. In this experiment, 1.7% of those who received and opened an email request for a donation and 7.8% of those who received a text message asking for a donation actually made a donation. Assume that the people who received these requests were randomly assigned to one of the two groups (email or text message) and suppose that the given percentages are based on sample sizes of 2,000 (the actual sample sizes in the experiment were much larger). (Let p1 be the proportion who make a donation after receiving an email, and p2 be the proportion who make a donation after receiving a text message.) Find the test statistic and P-value. (Use a table or SALT. Round your test statistic to two…
This question refers to a survey of a university's faculty members on affirmative action policies for the university. The survey was based on telephone interviews with a random sample of 1,001 faculty members conducted in December 1995. One of the questions asked was, "Do you favor or oppose using race, religion, sex, color, ethnicity, or national origin as a criterion for admission to the university?" Of the 704 male respondents, 45% said "Favor," and of the 297 female respondents, 72% said "Favor." (a) Find the conservative margin of error (in %) for the male respondents. (Round your answer to one decimal place.) % Use the conservative margin of error to compute an approximate 95% confidence interval for the percent who favored this policy at the time of the poll in the population of male faculty members.

Recently, the number of airline companies that offer in-flight Wi-Fi service to passengers has increased. However, it is estimated that only 10% of the passengers who have Wi-Fi available to them are willing to pay for it. Suppose Gogo, the largest provider of airline Wi-Fi service, would like to test this hypothesis by randomly sampling 125 passengers and asking them if they would be willing to pay $4.95 for 90 minutes of onboard Internet access. Twenty passengers indicated they would. Using α = 0.05, anwer the following questions: a. Based on this sample, can we conclude that the proportion of airline passengers willing to pay for onboard Wi-Fi service is different than 10%? b. Determine the p-value for this test.
In a study about learning styles, researchers used a group of 64 elementary school students who volunteered to be part of the study. The researchers gave each student a pre-test and based upon the results, they divided them into 32 pairs of similarly scoring students. School administrators then randomly assigned one student from each pair to mathematics instruction online while the other student received in-person instruction in a traditional classroom. At the end of the year, all 64 students received a mathematics assessment, measured on a 100-point scale. The researchers calculated the difference (in person −− online) in the mathematics assessment scores for each pair of students. The 32 differences had a mean of 15 and a standard deviation of 3.9 points. Construct and interpret a 95% confidence interval for the mean difference (in person −− online) in the mathematics assessment scores for all pairs of students like these who learn math either face-to-face or online.
Computer-mediated communication (CMC) is a form of interaction that heavily involves technology (e.g., instant messaging, email). A study was conducted to compare relational intimacy in people interacting via CMC to people meeting face-to-face (FTF). Participants were 48 undergraduate students, of which half were randomly assigned to the CMC group and half assigned to the FTF group. The variable of interest, relational intimacy score, was measured (on a 7-point scale) for each participant after each of three different meeting sessions. Summary statistics for the first meeting session are given here. The researchers hypothesized that, after the first meeting, the mean relational intimacy score for participants in the CMC group would be lower than the mean relational intimacy score for participants in the FTF group. Test the researchers’ hypothesis using α = .10. CMC FTF Number…
