Urban Travel Times Population of cities and driving times are related, as shown in the accompanying table, which shows the 1960 population N, in thousands, for several cities, together with the average time T, in minutes, sent by residents driving to work. City Population N Driving time T Los Angeles 6489 16.8 Pittsburgh 1804 12.6 Washington 1808 14.3 Hutchinson 38 6.1 Nashville 347 10.8 Tallahassee 48 7.3 An analysis of these data, along with data from 17 other cities in the United States and Canada, led to a power model of average driving time as a function of population. a Construct a power model of driving time in minutes as a function of population measured in thousands b Is average driving time in Pittsburgh more or less than would be expected from its population? c If you wish to move to a smaller city to reduce your average driving time to work by 25, how much smaller should the city be?
One of the main issues that censuses are not considered as a feasible option for studies beside being logistically demanding is: Select one: a. Populations contains too many variables and cannot be analyzed. b. Censuses are not accurate because we cannot use statistics with it. c. None of the mentioned reasons is a valid reason. d. Samples are easier to work with than census that is what makes use samples. e. Populations are dynamic and very rarely stand still.
The effect of aid is a subject of considerable academic and policy interest. In this question we examine the relationship between foreign aid and civil conflict using a recent paper by Crost et al. (2014) in the Philippines. The authors collect data on civil conflict related incidents at the municipality level as well as information on aid receipts at the municipality level. The conflict data was collected from the Philippine military and provides casualty counts (as well as the party responsible) by municipality. Aid in this context refers to a large anti-poverty program (the KALAHI-CIDSS) funded by the World Bank and run from 2003-2008. The program provided cash grants to municipalities to build infrastructure such as roads, water-systems, clinics and schools. The grants were fairly large and accounted for approximately 15% of the annual budget for the average municipality. (a) Let Yi denote the number of conflict casualties in municipality i in a given timeperiod after the…
Activity Limitations. The National Center for Health Statistics compiles information on activity limitations. Results are published in Vital and Health Statistics. The data show that 13.6% of males and 14.4% of females have an activity limitation. Are gender and activity limitation statistically independent? Explain your answer.
Study 1. Hunger and Psychological Distress A study was done to determine if food insecurity/hunger impacts psychological distress (this is fake data to make it simple, but it is based off of a 2020 study that examined the associations between food insecurity and psychological distress among older people in Ghana). Participants were broken into three groups based on their responses: no food insecurity, moderate food insecurity, and severe food insecurity. Psychological distress was measured on the Kessler Psychological Distress Scale (K10), where scores range from 0 to 50. Enter data and test to determine if there is a significant difference between the 3 groups in psychological distress. Food insecurity: Psychological distress scores (higher = more distress) No food insecurity 5 6 8 10 5 4 14 9 Moderate food insecurity 16 14 9 7 14 8…
Suppose that as part of a research methods class, Bailey was asked to write summaries of research papers on the following topics. • The effects of increasing temperatures on the migration patterns of birds • The effects of media coverage on community support for crime prevention For each topic, identify the explanatory and the response variables. Temperature and the level of community support for crime prevention are the explanatory variables, and the amount of media coverage and the migration patterns of birds are the response variables. Temperature and the amount of media coverage are the response variables, and the migration patterns of birds and the level of community support for crime prevention are the explanatory variables. Temperature and the amount of media coverage are the explanatory variables, and the migration patterns of birds and the level of community support for crime prevention are the response variables.

Match the description on the right with the correct term on the left regarding types of forecasting methods. 1. Econometric, input-output, and simulation are techniques used with this type of forecasting method, which assumes that the variable to be forecasted is related to one or more intrinsic variables. Causal Methods 2. The Delphi technique, market surveys, and life-cycles analogy are techniques used with this type of forecasting method, which relies on the judgment of individuals or Qualitative Methods Time-Series Methods groups. 3. Moving averages and exponential smoothing are techniques used with this type of forecasting method, which assumes that time is the only important variable.
