The National Electronic Injury Surveillance System tracks injuries reported from hospital admissions across the United States (Consumer Product Safety Commission 2018). For the data in 2017, we extracted all incidences of hand injuries that referenced punching a wall. There were 1843 such cases. The surveillance system also records some of the properties of the patients, including gender. Of all cases where a person was admitted to a hospital for injuries from punching a wall, 1352 were recorded as male and 491 were recorded as female. a. Do an appropriate hypothesis test to ask whether the proportion of males among wall-punchers is 50%.

a. Do an appropriate hypothesis test to ask whether the proportion of males among
wall-punchers is 50%.

A researcher at the Sloan-Kettering Cancer Research Center was once criticized or falsifying data.

Suppose you are conducting a study about how the average U.S. worker spends time over the course of a workday. You are interested in how much time workers spend per day on personal calls, e-mails, and social networking websites, as well as how much time they spend socializing with coworkers versus actually working. The most recent census provides data for the entire population of U.S. workers on variables such as travel time to work, time spent at work, and break time at work. The census, however, does not include data on the variables you are interested in, so you obtain a random sample of 82 full-time workers in the United States and ask about personal calls, e-mails, and so forth. You are curious about how your sample compares with the census, so you also ask the workers the same questions about work that are asked in the census. Suppose the mean break time per day from the most recent census is 29.6 minutes, with a standard deviation of 16.0 minutes. Your sample of 82 U.S. workers…

Is this an observational study or an experiment? Why? Identify the sample and population of this study. In order to match the demographics of the company, the researcher wants 10% of the sample to be management and 90% to not be. How can this be done using stratified sampling? The researcher also decides to keep track of subjects' age. This would be considered: stratifying, bias, blocking, control? If the researcher removed all employees of Asian descent from the sample, what is this considered?
In 2007, a university study was published investigating the crash risk of alcohol impaired driving. Data from 2871 crashes were used to measure the association of a person's blood alcohol level (BAC) with the risk of being in an accident. The table below shows the results from the study the relative risk is a measure of how many times more likely a person is to crash. So, for example, a person with a BAC of 0.09 is 3.54 times as likely to crash as a person who has not been drinking alcohol. BAC 0 .01 .03 .05 .07 .09 .11 .13 .15 .17 .19 .21 risk 1 1.03 1.06 1.38 2.09 3.54 6.41 12.6 22.1 39.05 65.32 99.78 Find the best fit exponential model for the risk of having an accident based on your BAC.

We often describe our emotional reaction to social rejection as “pain.” A clever study asked whether social rejection causes activity in areas of the brain that are known to be activated by physical pain. If it does, we really do experience social and physical pain in similar ways. Subjects were first included and then deliberately excluded from a social activity while changes in brain activity were measured. After each activity, the subjects filled out questionnaires that assessed how excluded they felt. Here are data for 13 subjects. The explanatory variable is “social distress” measured by each subject’s questionnaire score after exclusion relative to the score after inclusion. (So values greater than 1 show the degree of distress caused by exclusion.) The response variable is change in activity in a region of the brain that is activated by physical pain. create a scatterplot
x Resorts & Spas, a magazine devoted to upscale vacations and accommodations, published its Reader's Choice List of the top 20 independent beachfront boutique hotels in the world. The data shown are the scores received by these hotels based on the results from Resorts & Spas' annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a hotel as excellent or very good on one of three criteria (comfort, amenities, and in-house dining). An overall score was also reported and used to rank the hotels. The highest ranked hotel, the Muri Beach Odyssey, has an overall score of 94.3, the highest component of which is 97.7 for in-house dining. If required, round your answer to three decimal places.

A researcher wanted to know whether the level of frustration over high gas prices differed for different types of vehicle owners. Following a sharp increase in the price of gas, the researcher asked 30 people to indicate their level of frustration with prices at the pump (frustration scores ranged from 1 to 10, with higher scores indicating greater frustration). Ten people were surveyed who owned a motorcycle as their primary means of transportation (coded a 1 in the data file 1), 10 were surveyed who owned a hybrid vehicle (coded a 2 in the data file 1), and 10 were surveyed who owned a non-hybrid vehicle (coded a 3 in the data file Exam 3). a.State the null and alternative hypotheses. b. State a research question for the data.
The administrators of a Faculty A were interested to understand personal characteristics of their students. They decided to conduct a survey and managed to get randomly 1625 students to respond to the survey. The same survey has been conducted for 3 years in a row and a summary report on students’ characteristics was produced. The first part of the survey was asking demographics questions on the students. The data in Table 1 show eight variables, each describing a different characteristic of the students taking the survey. For the data in the table, the description of the data is as follows: ID : An identifier for each of the individuals in the study. Gender : M for male and F for female Mathematics : To measure how much the student likes Mathematics courses (Really Don’t Like it, Not too much, I like it, Absolutely love it) Exercise : Number of times spent exercising per week Games : Number of hours spent playing online games per week GPA…
