- Over the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 96% as of 2015.† With this increase in the use of home smoke detectors, what has happened to the death rate from home fires? Suppose the following contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population. Percentage ofHomes withSmoke Detectors Home Fire Deathsper Millionof Population 0.52 22.8 0.69 20.7 0.76 17.2 0.78 20.4 0.79 19.3 0.84 18.8 0.83 17.5 0.87 16.1 0.88 13.5 0.90 14.3 0.92 14.2 0.94 12.9 0.95 10.8 0.96 10.8 0.97 10.1 0.96 8.3 0.96 8.0 (a) Do you expect a positive or negative relationship between smoke detector use and deaths from home fires? Why or why not? We would expect there would be a ---Select--- negative positive relationship between smoke detector use and deaths from home fires. As more households have…The diagram below illustrates the electricity generation in ten countries during 2011. (a) Based on the data in the graph, identify one of the fuel sources that in 2011 was intermediate in contribution among the ten countries in the amount of electricity generated. (b) Based on the data in the graph, identify the country that produced a higher percentage of its electricity in 2011 from nonhydroelectric renewables than any other country. (c) Based on the data in the graph, describe one environmental problem in South Korea that could result if its total electricity generation was increased by 10 percent with its most-used fuel source. (d) Based on the data in the graph, propose a solution to reduce an environmental problem linked to the primary means of electricity generation in Brazil, other than reduced use of that resource. (e) The ecological footprint of an average individual living in Canada is seven times larger than the ecological footprint of an average individual living in…In February 2021, the Chicago Tribune reported:“The overdose epidemic that has ravaged Chicago has not spared the nearby suburbs, some of which have death rates comparable to anything seen in the city, according to a report released this week by the Cook County Department of Public Health. ZIP codes in the towns of Worth, Broadview, Maywood, and Forest Park, areas that “have substantially lower median household incomes and higher poverty rates,” have been especially hard-hit, the report said.”In the article, they claimed that lower incomes were associated with higher overdose death rates and that overdose death rates are increasing over time. The data you have been analyzing wasn’t focused on Chicago, obviously. But do your results support the general gist of the statistical argument being made in this Tribune excerpt? Please address:• Do overdose death rates appear to be associated with per capita income (use scatterplot)?• Do overdose death rates appear to be increasing over time…
- According to an article by Hiroko Tabuchi and Michael Corkery, in the New York Times, “Exports of US plastic garbage rise, despite ban.” When more than 180 nations agreed last year to place strict limits on exports of plastic waste from richer countries to poorer ones, the move was seen as a major victory in the fight against plastic pollution. [But,] Data for January showed that exports of scrap plastic from the United States edged upward, to 48 million tons from 45 million tons the previous January. Exports to poorer nations were virtually unchanged from a year ago, totaling 25 million tons. Advocates say that there are clear red flags in the data. Malaysia, which had signed on [to the agreement], remained a major destination for US scrap plastic in January. a. How many pounds did each American contribute on average to the amount of scrap plastic exported from the USA to poorer nations like Malaysia in 2020? Type your work and answer here: b. What was the percent (%) increase in…A company studied the number of lost-time accidents occurring at its Brownsville, Texas, plant. Historical records show that 6% of the employees suffered lost-time accidents last year. Management believes that a special safety program will reduce such accidents to 5% during the current year. In addition, it estimates that 15% of employees who had lost-timeaccidents last year will experience a lost-time accident during the current year. a. What percentage of the employees will experience lost-time accidents in both years?b. What percentage of the employees will suffer at least one lost-time accident over the two-year period?Suppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table. Population Populationdescription Population mean(unknown) Samplesize Sample mean(min) Sample standarddeviation (min) 11 male μ1 n=15 x¯1=137.7 s=51.7 22 female μ2 n=15 x¯2=114.6 s=34.2 df=24.283 The population standard deviations are unknown and unlikely to be equal, based on the sample data. Laura plans to use the two-sample ?-t-procedures to estimate the…
- The National Highway Association is studying the relationship between thenumberof bidders on a highway project and the winning (lowest) bid for the project. Ofparticular interest is whether the number of bidders increases or decreases the amountof the winning bid.One major factor in low productivity is the amount of time wasted by workers. Wasted time could include things such as time spent waiting for more material and equipment, cleaning up mistakes, and performing any other activity not related to production. In a project designed to examine this problem, a consultant took a survey of 200 workers in companies that were classified as successful (on the basis of their latest annual profits) and another 200 workers from unsuccessful companies. The amount of time (in hours) wasted during a standard 40-hour workweek was recorded for each worker. Do these data provide enough evidence at the 5% significance level to infer that the amount of time wasted in unsuccessful firms exceeds that of successful ones? To answer this question, the consultant ran several analyses and provided the out below. Note that none of these analyses might be correct. A. H0: (μ1 - μ2) = 0 H1: (μ1 - μ2) > 0 B. H0: μD = 0 H1: μD > 0 C. H0: μD = 0…Suppose, a small town has 15000 people. Among the inhabitants, a pair is recently affected by a contagious disease. An affected pair can not transmit the disease until the pair is suffering for two days. After two days of sufferings, the pair can transmit the disease to another pair in each subsequent day. So, what percentage of the population will be affected after 22 days? Consider counting the number of affected people from day 1. Explain each step thoroughly, as your grade in this question will largely depend on the details of your explanation.
- In 2010, MonsterCollege surveyed 1250 U.S.college students expecting to graduate in the next several years.Respondents were asked the following question:What do you think your starting salary will be at your firstjob after college?The line graph shows the percentage of college students who anticipated various starting salaries.What starting salaries were anticipated by more than 20% of college students?A Gallup survey showed that in March 2011 , 8 of every 25 employers in the United States were adding more workers to their workforce, 9 of 50 were reducing their workforce, and 1 of 2 were keeping it the same. In a metropolitan area there are 1250 employers and of those who will hire, they will hire an average of seven new employees. If the employers who were cutting their workforce in that area were planning on letting go an average of nine workers, what would the net change in jobs for the area be? This metropolitan area would see a ▼net decrease or increase of jobs.
