The General Social Survey is an annual survey given to a random selection of about 1500 adults in the United States. Among the many questions asked are "What is the highest level of education you've completed?" and "If you're employed full-time, how many hours do you spend working at your job during a typical week?" We're interested in examining whether or not there are differences in the typical work week length based on the level of education of the worker. We perform a one-way, independent-samples ANOVA test, with the "groups" in the ANOVA being categories of highest educational degree of the worker ("less than high school," "bachelor's degree," etc.) and the variable being the number of hours written down by the worker in answering the survey question.
Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 12.8 million out of the 312.7 million Americans suffer from sleep apnea, or approximately 4.1%. A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population’s percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 4.1%, a simple random sample of 392 commercial truck drivers is examined by a medical expert, who concludes that 2424 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 4.1%? Use a 0.02 level of significance. Step 3 of 3 : Draw a conclusion and interpret the decision. 1.…
A certain disease has an incident rate of 0.5%. If the false negative rate is 4% and the false positive rate is 1%, compute the probability that a person who tests positive actually has it. Make the answer a percent to one place after the decimal.
When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 974 comma 168 radioactive atoms, so 25 comma 832 atoms decayed during 365 days. a. Find the mean number of radioactive atoms that decayed in a day. (Round to three decimal places as needed.) b. Find the probability that on a given day,52 radioactive atoms decayed. (Round to six decimal places as needed.)

TIME WASTED AT WORK? An employment survey at a local small business was conducted to see how much time is wasted at work by employees during an 8-hour workday. Below are the results of a random sample of 10 employees employed at this small business who were asked to truthfully and anonymously record how much time in minutes is wasted in an 8-hour workday. The owner of the small business claims less than 115 minutes is wasted in an 8-hour workday. Does this data provide evidence to support the claim that employees waste less than 115 minutes in an 8-hour workday at α=.05? 108 112 117 130 111 131 113 113 105 128 Demonstrate this sample came from an approximately normal population by producing a graph.

On average, 40 jobs arrive per day at a factory. The time between arrivals of jobs is exponentially distributed. The factory can process an average of 42 jobs per day, and the time to process a job is exponentially distributed. a. On average, how long does it take before a job is completed (measured from the time the job arrives at the factory)? b. What fraction of the time is the factory idle? c. What is the probability that work on a job will begin within two days of its arrival at the factory?

A research group conducted an extensive survey of 2929 wage and salaried workers on issues ranging from relationships with their bosses to household chores. The data were gathered through hour-long telephone interviews with a nationally representative sample. In response to the question, "What does success mean to you?" 1571 responded, "Personal satisfaction from doing a good job." Let p be the population proportion of all wage and salaried workers who would respond the same way to the stated question. Find a 90% confidence interval for p.
