4.22 : I've posted an image of the question. 4.22 How will marketers change their organic (unpaid) socialmedia postings in the near future? A survey by Social Media Exam-iner reported that 65% of B2B marketers (marketers who focus pri-marily on attracting businesses) plan to increase LinkedIn organicsocial media postings, as compared to 43% of B2C marketers (mar-keters who primarily target consumers). The survey was based on1,947 B2B marketers and 3,779 B2C marketers. The following tablesummarizes the results.BUSINESS FOCUSINCREASE LINKEDINPOSTINGS?B2BB2CTotalYes1,2661,6252,891No6812,1542,835Total1,9473,7795,726Source: Data extracted from "2018 Social Media Marketing Industry Report,"socialmediaexaminer.com.a.

A student researcher was surprised to learn that the 2017 NCAA Student-Athlete Substance Use Survey supported that college athletes make healthier decisions in many areas than their peers in the general student body. He collected data of his own, focusing exclusively on male student-athletes to see if such habits vary based on one’s sport. He asked 93 male student-athletes whether they had engaged in binge-drinking in the last month (> 5 drinks in a single sitting).

Most air travelers now use e-tickets. Electronic ticketing allows passengers to not worry about a paper ticket, and it costs the airline companies less to handle than paper ticketing. However, in recent times the airlines have received complaints from passengers regarding their e-tickets, particularly when connecting flights and a change of airlines were involved. To investigate the problem, an independent watchdog agency contacted a random sample of 20 airports and collected information on the number of complaints the airport had with e-tickets for the month of March. At the .05 significance level, can the watchdog agency conclude the mean number of complaints per airport is less than 15 per month? What assumption is necessary before conducting a test of hypothesis? Is it reasonable to conclude that the population follows a normal distribution? Conduct a test of hypothesis and interpret the results. The information is reported below: 14 12 14 15 16 5 15 12 14 12 13 14 12 13 13 12 16…
The American College Health Association produced the National College Health Assessment (Andy Gardiner, "Surfacing from Depression," February 6, 2006). The assessment indicates that the percentage of U.S. college students who report having been diagnosed with depression has risen from 2000. The assessment surveyed 47,202 students at 74 campuses. It discovered that 10.3% and 14.9% of students indicated that they had been diagnosed with depression in 2000 and 2004, respectively. Assume that half of the students surveyed were surveyed in 2004. Conduct a hypothesis test to determine if there has been more than a 0.04 increase in the proportion of students who indicated they have been diagnosed with depression. Use a significance level of 0.05 and a p-value approach to this test.
A recent PwC survey of 1,379 CEOs from a wide range of industries representing a mix of company sizes from Asia, Europe, and the Americas indicated that CEOs are firmly convinced that it is harder to gain and retain people's trust in an increasingly digitalized world (pwc.to/2jFLzjF). Fifty-eight percent of CEOs are worried that lack of trust in business would harm their company's growth. Which risks arising from connectivity concern CEOs most? Eighty-seven percent believe that social media could have a negative impact on the level of trust in their industry over the next few years. But they also say new dangers are emerging and old ones are getting worse as new technologies and new uses of existing technologies increase rapidly. CEOs are particularly anxious about breaches in data security and ethics and IT outages and disruptions. A vast majority of CEOs are already taking steps to address these concerns, with larger-sized companies doing more than smaller-sized companies. a.…
In a survey of 1000 adult Americans, 45.9% indicated that they were somewhat interested or very interested in having web access in their cars. Suppose that the marketing manager of a car manufacturer claims that the 45.9% is based only on a sample and that 45.9% is close to half, so there is no reason to believe that the proportion of all adult Americans who want car web access is less than 0.50. Is the marketing manager correct in his claim? Provide statistical evidence to support your answer. For purposes of this exercise, assume that the sample can be considered as representative of adult Americans. Test the relevant hypotheses using ? = 0.05. a. Find the test statistic and P-value.

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in the U.S. in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumers ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a different proportion of identity theft than 23%? Test at 5% level.

6.59 US Postal Service's performance. The US Postal Service (USPS) reports that 95% of first-class mail within the same city is delivered on time (i.e., within 2 days of the time of mailing). To gauge the USPS performance, Price Waterhouse monitored the delivery of first-class mail items between Dec. 10 and Mar. 3-the most dif- ficult delivery season due to bad weather conditions and holidays. In a sample of 332,000 items, Price Waterhouse determined that 282,200 were delivered on time. Comment on the performance of USPS first-class mail service over this time period.

A sociologist wants to investigate the question, "Is there a relationship between texting during class and grade-point-average (GPA) among high school seniors in a large district?" Which study design is most appropriate? Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester, obtain each student’s GPA from the appropriate admissions and records office. Compare the GPA of students who routinely text during class to the GPA of students who do not text during class. Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester,…
According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumer complaints ("Consumer fraud and," 2008). Do these data provide enough evidence to show that Arkansas had a higher proportion of identity theft than 23%? Test at the 5% level.
