Suppose you are conducting a study about how the average US worker spends time over the course of a workday. You are interested in how much time workers spend per day on personal calls, emails, 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 US 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 102 full-time workers in the United States and ask about personal calls, emails, 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 travel time to work from the most recent census is 24.1 minutes, with a standard deviation of 4.5 minutes. Your sample of 102 US workers…

The report documents that 70% of older workers in England feel fulfilled, compared with just 50% of younger workers. A demographer believes that an identical pattern does not exist in Asia. A survey of 120 older workers in Asia finds that 75 feel fulfilled. A similar survey finds that 58% of 210 younger workers feel fulfilled. (You may find it useful to reference the appropriate table: z table or t table) At the 5% level of significance, test if older workers in Asia feel less fulfilled than their British counterparts. a-1.

Power and Associates use the proportion of owners likely to repurchase a particular automobile as an indication of customer loyalty for the automobile. An automobile with a greater proportion of owners likely to repurchase is concluded to have greater customer loyalty.

The study contained 500 respondents and the data is summarized in the Microsoft Excel Online file below. Use the spreadsheet to perform the required calculations and hypothesis test.arrow_forward
- A Harris Interactive poll reported that 32.4% of 275 randomly selected Americans living in the west stated that they attend church regularly. Whereas, 57.6% of 264 randomly selected Americans living in the south stated that they attend church regularly. Based on the results of this poll, can one reach the conclusion that the proportion of Americans who attend church regularly is lower in the west than in the south?
