- As you read about each study, (a) classify the type of research that it reflects, and (b) identify the kinds of conclusions that might reasonably be drawn from the results. The director of computer technology in Emerson School District wants to gather information about the use of technology-based instruction in language arts and literature classes in the district's middle schools and high schools. For her study, the director identifies five of the top teachers in these content areas. She visits and observes each teacher's classes on three different days and subsequently interviews each teacher. Then she summarizes the ways that these teachers incorporate the use of technology into their lessons and their students' activities. The director also summarizes teachers' beliefs about the roles of technology in students' learning and motivation. (a) Classify the research as one of the following: Quantitative/descriptive Quantitative/correlational…arrow_forwardA company studied the number of lost-time accidents occurring at its Brownsville, Texas, plant. Historical records show that 10% of the employees suffered lost-time accidents last year. Management believes that a special safety program will reduce such accidents to 7% during the current year. In addition, it estimates that 15% of employees who had lost-time accidents 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 (to 2 decimals)? % b. What percentage of the employees will suffer at least one lost-time accident over the two-year period (to 2 decimals)?

To investigate this, you bring 31 different cars to two different garages, Bubba's Hubcap Heaven and Repair, and Merle's Motor Shop. Some of the cars need lots of repairs. Some of the cars need very few. By taking each car to both shops, we can directly compare the two sets of prices. The dataset is in an Excel file named "Bubba_v_Merle_3190.xls", which you can find in the "Data" folder under Course Documents. Before running your analysis, be sure to look at the data file and verify that each car requires a different amount of repairs, and that prices in one shop are correlated with prices at the other shop. That is, they're in the same ballpark. The question is whether one tends to charge more, on average, than the other. Your task is to use Excel to test the research hypothesis that prices are different in the two shops; the null hypothesis is that prices are…arrow_forward
- The director of a large public library must schedule employees to reshelf books and periodicals checked out of the library. The number of items checked out will determine the labor requirements. The following data reflect the number of items checked out of the library for the past three years: Month Year 1 Year 2 Year 3 January February March April May 1,733 2,676 2,417 2.432 2 421 2,053 2,321 2,359 2,088 2 692 2,132 2,564 2,677 2,150 2,243 2,692 2,421 2,378 2,239 2,445 June 2,122 2,206 July August September October 1,869 2,506 2,291 2,378 2,189 2,663 2,039 1,678 1,699 2,065 2,113 2,404 1,903 1,922 November 2,399 2,274 December The director needs a time-series method for forecasting the number of items to be checked out during the next month. Suppose that the director considers the best forecast to be the one that minimizes the absolute value of mean bias (E). Find the best simple moving average forecast you can using the director's criteria. Using the director's criteria, the best…arrow_forwardEach year a market research company surveys new car owners 90 days after they purchase their cars. This data is used to rate auto brands (such as Toyota and Ford) on quality and customer satisfaction. Suppose the following were the quality rating and satisfaction scores for 30 brands sold in the United States. Brand Quality Rating Satisfaction Rating Acura 64 814 Audi 80 863 BMW 76 849 Buick 74 792 Cadillac 58 826 Chevrolet 64 791 Chrysler 58 783 Dodge 58 790 Fiat 38 768 Ford 66 789 GMC 60 791 Honda 71 783 Hyundai 70 804 Infiniti 63 821 Jeep 43 762 Kia 72 791 LandRover 55 858 Lexus 76 844 Lincoln 65 835 Mazda 74 790 Mercedes-Benz 67 842 MINI 68 795 Mitsubishi 51 748 Nissan 63 786 Porsche 76 882 Scion 65 779 Subaru 78 766 Toyota 72 783 Volkswagen 67 796 Volvo 69 812 (a) Construct a scatterplot of y = satisfaction rating versus x = quality rating.

Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948. If you were working for a national survey organization doing a general public survey of young adults and older adults, what topics and questions would you design into your survey to elaborate on this finding?arrow_forwardPart 1: The state of Maryland's arrest rate for marijuana possession in 2010 was the fourth highest in the nation. Public records for that year show that police arrested one out of every 250 Maryland residents for possession of marijuana. In addition, while Black people only comprised 30% of the State's population in 2010, 58% of those arrested for marijuana possession were Black. Use the following labels for events describing Maryland residents in the year 2010. M-AMP: Maryland resident was arrested for marijuana possession M-B: Maryland resident was a Black person a) What is the probability that a Maryland resident was arrested for marijuana possession in 2010? b) Use probability notation to express the cited percent values. 30% = P( 58% = P( c) Which of the values cited should be compared to determine whether race and arrests for marijuana possession in the state of Maryland in 2010 are independent?arrow_forward
