What is the Beta that shows the strongest controlled association?
It was reported that only one job vacancy was available for three recent college graduates. The main reason is that there is an excess of college graduates and a weak national economy. A survey of 100 recent graduates from your college reveals that 60 graduates have found work. At the 0.05 level of significance, can we conclude that the proportion of graduates who have found employment is greater?
An amusement park studied methods tor decreasıng the waiting time (minutes) for rides by loadıng and unloadıng riders more etticiently. Two alternative
loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the
method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to
the loading and unloading method, the type of ride, and interaction. Use a = 0.05.

- A recent study investigated the association between sudden cardiac death and smoking history in women from a large health system. The epidemiologist reviewed the electronic health records of women who died from sudden cardiac death (n=80) and women who died of non-cardiac causes (n=80). The investigator then reviewed these records for smoking history (smoking 1+ pack/day and smoking <1 pack/day) and identified the following results.

Participants (n = 72) were randomly assigned either to a group that was put on the diet (Diet = Present) or to a group that was not put on the diet (Diet = Absent), and researchers wanted to know whether the diet had a significant impact on blood pressure.

- Androstenedione (andro) is a steroid that is thought by some athletes to increase strength. Researchers investigated this claim by collecting a random sample of men and randomly assigning half to receive andro and the other half to receive a placebo. One of the variables measured in the study was the increase in "lat pull down" strength (in pounds) of each subject after 4 weeks. (A lat pull down is a type of weightlifting exercise.) Suppose the researchers wanted to conduct a hypothesis test to compare the increase in lat pull down strength between the two groups at a 0.10 significance level using a directional alternative (that andro increases lat pull down strength more than placebo). Which test(s) could be used? (Select all that apply.) OA. Paired Sample t Test OB. Wilcoxon-Mann-Whitney Test OC. Chi-Square Goodness-of-Fit Test OD. Binomial Test for p DE. Two Sample t Test OF.

You go to a center where experienced Tibetan Buddhist meditators regularly practice. You randomly select 10 of these people to participate in your experiment. Your dependent variable is the number of digits recalled from iconic memory. You test them before and after a 5 weeks' intensive meditation course. You predict that their iconic memory will be enhanced (better recall) as a result of the attentional training that the meditation gives. Here is the data you collect: Before: 6;6;6;7;5;7;5;5;6;6 After: 8;7;7;8;7;8;6;7;6;8 1. What is the null hypothesis? What is the alternative hypothesis? (use symbols and not words)arrow_forward
- Allopurinol test is often used as a screening device of potential carriers whose relatives are OTCD (a disorder of the urea cycle) patients. The sensitivity and the specificity of the allopurinol test are estimated as 0.927 and 0.997, respectively. If the prevalence of individuals with OTCD in the population is 1/32000, determine the predictive value negative of the allopurinol screening test.arrow_forwardBenzene is a pollutant that, according to studies, can be associated with health problems. Benzene is found in air, water, and soil and comes from both industrial and natural sources. Benzene levels in indoor air are generally higher than outdoors. The main source of benzene in indoor air appears to be tobacco smoke, thus the combustion of tobacco is a major source of pollution. Benzene levels are measured in a random sample of 36 bars in a city, obtaining an average benzene level of 19.2 mg / m3, with a standard deviation of 2.1 mg / m3. Estimate the mean benzene level in bars in this city using a 95% confidence interval.
