Concur Technologies, Inc., is a large expense-management company located in Redmond, Washington. The Wall Street Journal asked Concur to examine the data from 8.3 million expense reports to provide insights regarding business travel expenses. Their analysis of the data showed that New York was the most expensive city, with an average daily hotel room rate of $198 and an average amount spent on entertainment, including group meals and tickets for shows, sports, and other events, of $172. In comparison, the U.S. averages for these two categories were $89 for the room rate and $99 for entertainment. The table in the Excel Online file below shows the average daily hotel room rate and the amount spent on entertainment for a random sample of 9 of the 25 most visited U.S. cities (The…
In the book Business Research Methods (5th ed.), Donald R. Cooper and C. William Emory discuss studying the relationship between on-the-job accidents and smoking. Cooper and Emory describe the study as follows:
Suppose a manager implementing a smoke-free workplace policy is interested in whether smoking affects worker accidents. Since the company has complete reports of on-the-job accidents, she draws a sample of names of workers who were involved in accidents during the last year. A similar sample from among workers who had no reported accidents in the last year is drawn. She interviews members of both groups to determine if they are smokers or not.
The sample results are given in the following table.

- In the COVID-19 data set, there are several questions that participants answer about the reactions of their government to the pandemic, as well as questions about their own well-being, in terms of measures of distress, such as anxiety and depression. This data was collected quite early in the pandemic, near the beginning of the first wave in late March. One might ask whether how one viewed their government might affect one's concerns about the health of their family and themselves. What type of procedure might you use to see whether there was an association between attitudes towards governtment and worries about health?

- Researchers investigated whether elementary school students from families in need would choose healthier lunch options if offered. A random sample of students receiving free-and-reduced lunch at five different Connecticut elementary schools were offered a choice between 2 lunch options. One was a typical school lunch prepared off and warmed on campus, while the other was a healthier school lunch made on campus from a variety of fruits, vegetables, and lean protein. For each child, researchers kept track of whether or not the child selected the healthier option. The research question was whether of not the healthier option would be selected less than the typical school lunch. More specifically, we will investigate whether the sample data provide strong evidence that the heather lunch is picked less than 50% of the time? The researchers found in their sample of 294 students that 134 picked the healthier option. The value of the sample proportion who selected the candy is therefore…arrow_forwardResearchers Kaitlin Woolley and Ayelet Fishbach (2019) told participants that they were participating in a study on the effects of Hunger.

Half of the participant-pairs were randomly assigned to share a plate of salsa and chips, and the other half of participant-pairs were randomly assigned to eat their own individual servings. More specifically, the researchers reported that "participants were run in pairs of strangers.

- During the Covid crisis, there were lockdowns and working-from-home, whichmade collecting data on unemployment more challenging. Researchers fromHeriot Watt University conducted a survey of 1,000 individuals in the labour forceto assess rise in unemployment in September 2020. The object was to find outwhether the unemployment rate had risen above a benchmark proportion of 5per cent of the labour force in Scotland. Of the surveyed persons, 60 reportedbeing unemployed in the week prior to the survey.(i) Conduct a two-tailed test of whether unemployment rate during this periodwas 5 per cent. Set out your null and alternative hypotheses, significancelevel, test statistic, assumptions and sampling distribution clearly.

Magee discusses monitoring cost variances. A cost variance is the difference between a budgeted cost and an actual cost. Magee describes the following situation: Michael Bitner has responsibility for control of two manufacturing processes. Every week he receives a cost variance report for each of the two processes, broken down by labor costs, materials costs, and so on. One of the two processes, which we'll call process A , involves a stable, easily controlled production process with a little fluctuation in variances. Process B involves more random events: the equipment is more sensitive and prone to breakdown, the raw material prices fluctuate more, and so on. "It seems like I'm spending more of my time with process B than with process A," says Michael Bitner. "Yet I know that the probability of an inefficiency developing and the expected costs of inefficiencies are the same for the two processes. It's just the magnitude of…arrow_forward
