A scientist is studying the relationship between stomach aches and headaches among students. On her survey, she asked if the participant had headaches that could be classified as “sudden,” “chronic,” or “none.” The survey also asked if the participant had stomach aches with answers of “yes” or “no.” From the survey she found: 14% have sudden headaches; 22% have chronic headaches; 15% have stomach aches; Of those with stomach aches, 1⁄3 have sudden headaches. Of those with no headaches, 1⁄8 have stomach aches. What is the probability that a randomly selected student from the survey did not have stomach aches, but they do have chronic headaches?
Suppose a survey of 899 college students who were asked about their smoking behavior. Of the students surveyed, 262 classified themselves as nonsmokers, but said "yes" when asked later in the survey if they smoked. These students were classified as "phantom smokers," meaning that they did not view themselves as smokers even though they do smoke at times. The authors were interested in using these data to determine if there is convincing evidence that more than 25% of college students fall into the phantom smoker category. Suppose that the sample of 899 college students can be regarded as representative of college students in the United States. (a) What hypotheses would you test to answer the question posed? H0: p = 0.25 versus Ha: p ≠ 0.25 H0: p ≠ 0.25 versus Ha: p = 0.25 H0: p = 0.25 versus Ha: p > 0.25 H0: p < 0.25 versus Ha: p > 0.25 H0: p = 0.25 versus Ha: p < 0.25 (b) Is the sample size large enough for a large-sample test for a population…

If a study determines the difference in average salary for subpopulations of people with blue eyes and people with brown eyes is NOT significant, then the populations of blue-eyed people and brown-eyed people are ________ different salaries. a) unlikely to have b) very unlikely to have c) guaranteed to have d) guaranteed to not have
Suppose we want to study the effect of smoking on lung capacity in women. Match the study to experimental or observational. Find 100 women age 20 who do not currently smoke. Randomly assign 50 of the 100 women to the smoking treatment and the other 50 to the no smoking treatment. Those in the smoking group smoke a pack a day for 10 years while those in the control group remain smoke free for 10 years. Measure lung capacity for each of the 100 women. Find 100 women age 30 of which 50 have been smoking a pack a day for 10 years while the other 50 have been smoke free for 10 years. Measure lung capacity for each of the 100 women. Analyze, interpret, and draw conclusions from data.

The permanent residence of adults aged 18-25 in the U.S. was examined in a survey from the year 2000. The survey revealed that 27% of these adults lived alone, 32% lived with a roommate(s), and 41% lived with their parents/guardians. In 2008, during an economic recession in the country, another such survey of 1600 people revealed that 398 lived alone, 488 lived with a roommate(s), and 714 lived with their parents. Is there a significant difference in where young adults lived in 2000 versus 2008 and state the p-value? Test with a Goodness of Fit test at α=0.05.

Determine the mean waiting time W for an M/M/2 system when lambda = 2 and μ = 1.2. Compare this with the mean waiting time in an M/M/1 system whose arrival rate is lambda = 1 and service rate is μ = 1.2. Since the arrival rate per server is the same in both cases and service times don’t vary, should the wait times be the same in both cases?
2. A leading researcher in the study of interstate highway accidents proposes that a major cause of many collisions on the interstates is not the speed of the vehicles but rather the difference in speeds of the vehicles. When some vehicles are traveling slowly while other vehicles are traveling at speeds greatly in excess of the speed limit, the faster-moving vehicles may have to change lanes quickly, which can increase the chance of an accident. Thus, when there is a large variation in the speeds of the vehicles in a given location on the interstate, there may be a larger number of accidents than when the traffic is moving at a more uniform speed. The researcher believes that when the standard deviation in speed of vehicles exceeds 10 mph, the rate of accidents is greatly increased. During a 1-hour period of time, a random sample of 50 vehicles is selected from a section of an interstate known to have a high rate of accidents, and their speeds are recorded using a radar gun. The data…
A researcher uses an anonymous survey to track the number of salmon caught in Gaspe. Based on a set of 115 surveys distributed to a select few of the many hundreds of anglers who fished Gaspe, it was determined that anglers caught an average of 2.3 salmon per week. For this study, the average of 2.3 salmon per week is an example of which one statistic parameter. population sample
