The dreaded disease brainfreezitis afflicts 2% of actuarial students taking an exam. Two tests are developed to detect this affliction. Test 1 gives positive results 98% of the time for an afflicted person and 4% of the time for a non-afflicted person. Test 2 gives positive results 99% of the time for an afflicted person and 6% of the time for a non-afflicted person. Given an afflicted person, the outcome of each test is conditionally independent of the other test; likewise for a non-afflicted person. If a randomly selected student tests positive with both tests, what is the probability that student actually has brainfreezitis?

If parallel components are used for any component with worse than a 1/10000 chance of failure, what is the overall reliability? Parallel components are used for any component with 1/10000 chance of failure, then the reliability is:
There have been many studies recently concerning coffee drinking and cholesterol level. While it is known that several coffee-bean components can elevate blood cholesterol level, it is thought that a new type of paper coffee filter may reduce the presence of some of these components in coffee. The effect of the new filter on cholesterol level will be studied over a 10-week period using 300 nonsmokers who each drink 4 cups of caffeinated coffee per day. Each of these 300 participants will be assigned to one of two groups: the experimental group, who will only drink coffee that has been made with the new filter, or the control group, who will only drink coffee that has been made with the standard filter. Each participant’s cholesterol level will be measured at the beginning and at the end of the study. Describe an appropriate method for assigning the subjects to the two groups so that each group will have an equal number of subjects. In this study, the researchers chose to include a…

Which test would you conduct to determine whether the change in cholesterol level would be greater if people used the new filter rather than using the standard filter? Why would the…
A hypothetical study looks at the effect of drinking alcohol on health. Across all genders and age groups, people who do not drink tend to be healthier on average than people who do drink. However, people who drink regularly are on average healthier than those people who have recently stopped drinking. Is it reasonable to conclude that for the sake of health, we should not start drinking, but if we have already started drinking alcohol, it is healthier to continue and not to stop?
A researcher conducted the first four steps of an Independent ANOVA, and on step 4 he Rejected H0, concluding that the drug had some overall effect. However, as we learned, Rejecting H0 is not really enough to call your study a “success” on ANOVA; you still need to check several more things in Step 5 and Step 6. So, let’s say the researcher gets the following APA table on Step 5. In which of the following cases would the drug shown on this APA table be considered a “success”? Small Dose of Drug Medium Dose of Drug High Dose of Drug M 27.00 22.00 11.00 SD 1.00 1.73 1.00 chocies More than one of the other three options could be considered a “success” with the APA table shown If the study was investigating a memory-improving pill where the D.V. is memory score If the study was investigating a pain-reduction pill where the D.V. is pain levels If the study was investigating a depression-fighting medication where the D.V. is depression

It has been hypothesized that allergies result from a lack of early childhood exposure to antigens. If this hypothesis were true, then we would expect allergies to be more common in very hygienic households with low levels of bacteria and other infectious agents. To test this theory, researchers at the University of Colorado sampled the houses of 61 children 9-24 months old and recorded two variables: (1) whether the child tested positive for allergies and (2) the concentration of bacterial endotoxin in the house dust (endotoxin units per ml, EU/ml)1. The following are the endotoxin levels at the homes of the 51 children tested negative for allergies. 708.23 911.60 976.81 1316.63 262.74 9772.08 370.76 229.16 2570.51891.19 3163.20 1777.65 1288.57 436.23 2631.63 1173.52 911.67 7942.42 740.32 356.92 1175.48 1480.55 2754.61 575.62 573.89 468.26 1000.71 364.22 1025.26 1022.04 645.41 363.57 977.47 1022.75 1860.63 371.13 174.73 399.68 1479.77 2882.96…
A stock market analyst examined the performance of the shares of a large number ofcorporations. When the performance of these stocks was investigated year later, it turned out that 25 % performed much better than the market average ; 25 % performed much worse ; and remaining shares performed about the same as the average . 40% of the stocks that performed much better than the market average were rated as " good buys ” by the analyst ; as were 20 % of those that did about as well as market average and 10 % of those that did much worse than market average . What is the probability that a stock rated as “ good buys ” by the analyst performed much better than theaverage ?
In one of their studies, Strayer and his students tested whether people would get better at driving while talking on a cell phone if they practiced doing so (Cooper & Strayer, 2008). They had participants drive in a simulator while talking on a hands-free cell phone and while not talking on a phone. The same people participated over several days, so they had a chance to practice this multitasking. On the first day, they were considered to be least experienced; on the last day, the most experienced. On the last day, they were tested in both a familiar environment and a slightly different driving environment to see if the first days of practice would transfer to a new context. The researchers collected data on how many collisions (accidents) the drivers got into on the simulator. All of the data is in the picture below!! Please answer the following questions about the study! 1. What kind of design is this? (put your answer in the form ___X___ 2. What are the Vs and their levels in…
A new chemotherapy drug is released to treat leukemia and researchers suspect that the drug may have fewer side effects than the most commonly used drug to treat leukemia. The two drugs have equivalent efficacy. In order to determine if a larger study should be conducted to look into the prevalence of side effects for the two drugs, set up a Mann-Whitney Utest at the alpha equals .05 level and interpret its results. Number of Reported Side-Effects Old Drug 0 1 3 3 5 New Drug 0 0 1 2 4 Old Drug New Drug Total Sample (Ordered Smallest to Largest) Ranks Old Drug New Drug Old Drug New Drug A) We fail to reject H0, which…
Using a theoretical framework from engineering sciences, the researcher believes that the physical set up of hospital rooms impacts rates of hand washing. After prolonged engagement, she observed the healthcare providers working on a medical/surgical floor of a hospital. As the result of her data analysis she purposefully selected 6 physicians, 10 nurses and 12 nursing aids to conducted in-depth interviews with. Subsequent to the analysis of that data she then purposefully selected 5 medical residents, 10 more nurses, the radiographers assigned to the portable imaging machine, and 15 patient transporters to conduct interviews with. She uses the data she collected and analyzed to develop a survey that she sent to 100 randomly selected hospitals across the northeast. What research design was used in this study? a. Mixed Methods b. Exploratory c. Convergent d. Explanatory
