12.74 (M3, M4, M5, P1) JaupsThe authors of the paper "Driving Performance While Usinga Mobile Phone: A Simulation Study of Greek ProfessionalDrivers" (Transportation Research Part F [2016]: 164–170)describe a study to evaluate the effect of mobile phone useby taxi drivers in Greece. Fifty taxi drivers drove in a driv-ing simulator where they were following a lead car. Thedrivers were asked to carry on a conversation on a mobilephone while driving, and the following distance (the distancebetween the taxi and the lead car) was recorded. The samplemean following distance was 3.20 meters and the samplestandard deviation was 1.11 meters.a. Construct and interpret a 95% confidence interval for u,the population mean following distance while talking ona mobile phone for the population of taxi drivers.b. What assumption must be made in order to generalizethis confidence interval to the population of all taxi driv-adi ers in Greece?

The researchers reported:" A 2x2 ANOVA revealed, first of all, a main effect for depletion, indicating that depleted individuals generated less ideas (M = 9.40, SD = 5.64) than non-depleted individuals (M = 12.44, SD = 7.34), F (1, 108) = 6.03, p = .016, n2 = .05. This effect was qualified by the expected interaction with [perseverance], F (1,108) = 4.52, p = .036, n2 = .05". What size are the effects for the main effect of depletion and for the interaction between depletion and perseverance, according to Cohen's conventions? a. These are small- to -medium effects b. These are non existent effects c. These are large effects d. We are unable to tell from from the n2 / r2 statistics

4) A medical researcher is interested in determining if there is a relationship between adults over 50 who exercise regularly and low, moderate, and high blood pressure. A random sample of 236 adults over 50 is selected and the results are given below. Test the claim that regular exercise and low, moderate, and high blood pressure are independent. Use alpha= 0.01 Blood pressure: Reg exercise: low 35, moderate 62, high 25 No reg. Exercise: low 21, moderate 65, high 28
Suppose a researcher is interested inthe effectiveness in a new childhood exercise program implemented in a SRS of schools across a particular county. In order to test the hypothesis that the new program decreases BMI (Kg/m2), the researcher takes a SRS of children from schools where the program is employed and a SRS from schools that do not employ the program and compares the results. Assume the following table represents the SRSs of students and their BMIs. Student intervention group BMI (kg/m2) Student control group BMI (kg/m2) A 18.6 A 21.6 B 18.2 B 18.9 C 19.5 C 19.4 D 18.9 D 22.6 E 24.1 F 23.6 A) Assuming that all the necessary conditions are met (normality, independence, etc.) carry out the appropriate statistical test to determine if the new exercise program is effective. Use an alpha level of 0.05. Do not assume equal variances.B) Construct a 95% confidence interval about your estimate for the average difference in BMI between the groups.
A study was conducted to explore workplace bullying in a community NHS trust. Staff were asked about whether workplace bullying had affected their working environment (Quine L, BMJ 1999; 318: 228-229). Those who had been bullied had lower levels of job satisfaction (mean 10.5 [SD 2.7] vs 12.2 [2.3], P<0.001) and higher levels of job-induced stress (mean 22.5 [SD 6.1] v 16.9 [5.8], P<0.001) than those who had not been bullied. Based on the above info, Select which of the following statement(s) you believe to be true You CAN SELECT MORE THAN 1. a. The P value for the comparison of job-induced stress was less than 0.001. This means that we cannot reject the null hypothesis at the 5% level of significance. b. P < 0.001 means that there is a less than 1 in 1000 chance that we would have obtained these results, or more extreme results, if the alternative hypothesis was true. c. There is a significant difference in the levels of job satisfaction between…
An article23 summarized results from the Nurses’ Health Study and the Health Pro- fessionals Follow-Up Study. The article reported (with RR = relative risk) that “Com- pared with nonregular use, regular aspirin use was associated with lower risk of overall cancer (RR 0.97; 95% CI 0.94, 0.99), which was primarily due to a lower incidence of gastrointestinal cancers, especially colorectal cancers (RR 0.81; 95% CI 0.75, 0.88).” Identify the response variables and the explanatory variable for these two results. Explain how to interpret the confidence interval about colorectal cancers. Would the association with overall cancer be considered (i) significant or non- significant? (ii) strong or weak? Explain. question 1 and 2

An experiment to determine if a migraine medication decreases a person's average number of monthly migraines is performed on 400 people who report they have several migraines a month. Researchers randomly assigned 200 people to the treatment group and 200 people to the control group. After the study, the researchers determined that 48 of the subjects in the treatment group and 28 of the subjects in the control group average fewer migraines per month. The data from the two groups are resampled 150 times, and the table shows the distribution of the differences of the proportions for the reconfigured treatment and control groups.
The paper “Effect of long-term blood pressure control on salt sensitivity” [Journal of Medicine (1997) 28:147–156] describes a study evaluating salt sensitivity (SENS) after a period of antihypertensive treatment. Ten hypertensive patients (diastolic blood pressure between 90 and 115 mmHg) were studied after at least 18 months on antihypertensive treatment. SENS readings, which were obtained before and after the patients were placed on an antihypertensive treatment, are given in the table. 'Before' 'After' 22.86 6.11 7.74 -4.02 15.49 8.04 9.97 3.29 1.44 -0.77 9.39 6.99 11.4 10.19 1.86 2.09 -6.71 11.4 6.42 10.7 a) Write the null and alternate hypotheses What test will be used to test the hypothesis and what assumptions are required? test them. Is there significant evidence that the mean SENS value decreased after the patient received antihypertensive treatment?
31% of all pygmy softshell tortoises have stripes on their shells. A herpetologist in Cititon collects a sample of 28 pygmy softshell tortoises and finds that 8 of them have stripes on their shells. Is there enough evidence to conclude, at a significance of alpha = 0.05, that the proportion of pygmy softshell tortoises in Cititon with stripes on their shells is less than 31%? What is the claim? What is the null hypothesis? What is the alternative hypothesis? What is the test statistic? What is/are the critical value(s)? Do we reject the null hypothesis? What conclusion do we draw? What is the P-value for the problem above?
Students in QSO 510 are assigned to observe the effect of various types of music on relaxation mood in patients who are in the early and middle stages of Alzheimer's disease at a certain Nursing Home facility. A number of patients were selected to participate in the study based on their stages of Alzheimer's disease. Three forms of music were tested: R&B, Blues, and Reggae. While listening to music, relaxation levels were recorded for the patients with a high score indicating a higher level of relaxation. Scores are recorded below. Group Reggae Blues R&B Early Stage Alzheimer's 2124221820 9121059 2926302426 Middle Stage Alzheimer's 2220251820 141811913 1518201319 Use Excel’s ToolPak to compute Two-Way ANOVA and submit your statistical output.
