Most air travelers now use e-tickets. Electronic ticketing allows passengers to not worry about a paperticket, and it costs the airline companies less to handle than paper ticketing. However, in recent timesthe airlines have received complaints from passengers regarding their e-tickets, particularly whenconnecting flights and a change of airlines were involved. To investigate the problem, an independentwatchdog agency contacted a random sample of 20 airports and collected information on the numberof complaints the airport had with e-tickets for the month of March. At the .05 significance level, can thewatchdog agency conclude the mean number of complaints per airport is less than 15 per month? Whatassumption is necessary before conducting a test of hypothesis? Is it reasonable to conclude that thepopulation follows a normal distribution? Conduct a test of hypothesis and interpret the results. The information is reported below:1412141516515121412131412131312161315101413

The Federal Bureau of Investigation (FBI), as part of its internal security mission, serves as a database for all the reported crimes committed in the United States. One question that might be of interest is does having more police officers reduce the number of homicides? To investigate this claim, the 2013 data from the twenty largest municipal cities was supplied by the FBI's Uniform Crime Report. Below are two observations from the dataset: > head (cities) City Pop Homicides Police Density MedHome Mayor 1 New York 8175.133 335 4.2595 27016.30 5.5390 1 2 Chicago 2695.598 414 4.4309 11843.58 1.8310 The variables included in the study are: Name of city Population of city in 1,000s of people Number of homicides in the year 2013 Number of police officers per 1,000 people Number of people per square mile Median home price in $100,000 1 if city has a "Strong Mayor" form of government; 0 if not City Рор Homicides Police Density MedHome Мayor Model: log(u;) = Bo + B1Police; + B2MedHome; +…
A University conducted a survey of its recent graduates to collect demographic and health information for future planning purposes as well as to assess students’ satisfaction with their undergraduate experiences. The survey revealed that a substantial proportion of students were not engaging in regular exercise, many felt their nutrition was poor and a substantial number were smoking. In response to a question on regular exercise, 60% of all graduates reported getting no regular exercise 25% reported exercising sporadically and 15% reported exercising regularly as undergraduates. The next year the University launched a health promotion campaign on campus in an attempt to increase health behaviours among undergraduates. The program included modules on exercise, nutrition and(3)L-27244 3 smoking cessation. To evaluate the impact of the program, the University again surveyed graduates and asked the same questions. The survey was completed by 470 graduates and the following data were…
Plastics which are no longer needed for current use end up being recycled, or incinerated, or discarded into landfills or the natural environment. According to the 2016- 17 Australian Plastics Recycling Survey, the term ‘recycling’ is used in the plastics industry “to cover a range of activities including collection, sorting, reprocessing, export for reprocessing and manufacture of new products.” In order to avoid double-counting materials, survey data is typically collected on the reprocessing stage, which is the stage where waste plastics are converted into a new product (may be finished or semi-finished).
A study was conducted to explore the prevalence and impact of sleep problems on various aspects of people's lives. Staff from a university in Melbourne, Australia were invited to complete a questionnaire containing questions about their sleep behaviour (e.g. hours slept per night), sleep problems (e.g. difficulty getting to sleep) and the impact that these problems have on aspects of their lives (work, driving, relationships). The sample consisted of 271 respondents (55% female, 45% male) ranging in age from 18 to 84 years (M=43.9yrs). A student researcher is interested in examining whether the participants in the study sleep for 8 hours a night, the recommended average for adults. id sex age weight height sleep 83 0 42 52 162 9 294 0 54 65 174 7 425 1 89 170 8 64 0 41 66 178 8 536 0 39 62 160 7.5 57 0 66 62 165 8 251 0 36 62 165 8 255 0 35 75 174 7 265 1 90 180 8 290 1 41 75 187 7 418 1 70 7.5 95 1 78 178 8 77 0 33 67 158 6.5 203 0 80 172.5 8…

I am having trouble solving this problem. Can you please provide me with some help. Thank you. I appreciate it. Peter D. Hart Research Associates conducted a survey of randomly selected U.S. registered votes to explore public opinion on federal funding for stem-cell research. The survey found that 56% of college-educated voters and 48% of voters without a college degree supported such funding. If the samples included 366 college-educated voters and 466 voters without a college degree, can these sample results be used to reject a "no difference in the population proportions" null hypothesis at the 5% significance level?
Gulf Real Estate Properties, Inc., is a real estate firm located in southwest Florida. The company, which advertises itself as "expert in the real estate market," monitors condominium sales by collecting data on location, list price, sale price, and number of days it takes to sell each unit. Each condominium is classified as Gulf View if it is located directly on the Gulf of Mexico or No Gulf View if it is located on the bay or a golf course, near but not on the Gulf. Sample data from the Multiple Listing Service in Naples, Florida, provided recent sales data for 40 Gulf View condominiums and 18 No Gulf View condominiums. Prices are in thousands of dollars. The data are shown in the following table. Gulf View Condominiums No Gulf View Condominiums List Price Sale price Days to Sell List Price Sale Price Days to Sell 495 475 130 217 217 182 379 350 71 148 135.5 338 529 519 85 186.5 122 95 239 150 552.5 534.5 552.5 534.5 95 334.9 334.9 505 165 ×Ô¶5±2259828846§§A**_¶****888*A***** 0 210…
Many freeways have service (or logo) signs that give information on attractions, camping, lodging, food, and gas services prior to off-ramps. These signs typically do not provide information on distances. An article reported that in one investigation, six sites along interstate highways where service signs are posted were selected. For each site, crash data was obtained for a three-year period before distance information was added to the service signs and for a one-year period afterward. The number of crashes per year before and after the sign changes were as follows. Before: 14 29 62 123 64 62 After: 15 27 41 84 76 71 (a) The article included the statement "A paired t test was performed to determine whether there was any change in the mean number of crashes before and after the addition of distance information on the signs." Carry out such a test. [Note: The relevant normal probability plot shows a substantial linear pattern.] State and test the appropriate hypotheses. (Use a = 0.05.)…
A statistician is advising the government on policy that aims to benefit small bakers. Before going to the government with advice, they seek out the opinion of bakery shop owners. They survey 300 small bakery shop owners and ask whether they believe that the proposed policy will help them. 65% of those surveyed stated that the proposed policy would help them. It is known that there is a total of 3,000 small bakery shop owners in the country. The statistician hopes to find strong evidence that the policy will benefit at least 60% of bakery shop owners. Conduct a hypothesis test at a 1 percent level. Do the findings provide strong evidence that at least 60% of bakery shop owners state that the policy will be beneficial?
