Dr. S. Oberman has the research hypothesis that drivers who have consumed one drink are actually slightly better (score higher on adriving test) than drivers who have had no alcohol. (One drink, she believes, makes them relaxed and not as nervous.) She tests this byhaving subjects take a standard driving test. We know that completely sober, college-student drivers score an average of 75 on this test,where high scores mean better driving.Lon Sum, Dr. S. Oberman's research assistant, draws a random sample of 64 from a population of college students, and gives them onedrink.

The concept of the "standard error" does not apply here.

Description: Dr. S. Oberman has the research hypothesis that drivers who have consumed one drink are actually slightly better (score higher on adriving test) than drivers who have had no alcohol. (One drink, she believes, makes them relaxed and not as nervous.)

The standard error can be calculated as: SE=sn Here, s= Standard deviation n = Sample size Substitute the given values to find the standard error for this test as follows: SE=sn=2464=3Hence, the value of standard error is, 3

Auditors must make judgments about various aspects of an audit on the basis of their own direct experience, indirect experience, or a combination of the two. In a study, auditors were asked to make judgments about the frequency of errors to be found in an audit. The judgments by the auditors were then compared to the actual results. Suppose the following data were obtained from a similar study; lower scores indicate better judgments. If answer is zero enter "0".

Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…
A team physician has determined that of all the athletes who were treated for minor back pain, 72% responded to an analgesic, 59% responded to a muscle relaxant, and 44% responded to both forms of treatment. What percent of the athletes who were treated responded to the muscle relaxant but not to the analgesic? What percent of the athletes who were treated did not respond to either form of treatment?
Say Dr. Callahan measures her students' levels of narcissism. Her findings reveal that narcissism rates are higher in her male students versus her female students, a finding that is consistent with previous research. She also finds that the overall class average (11.5 out of 20) is lower than typical undergraduates' levels (15.5). Which of the following statements about this scenario is TRUE? She can conclude that being a SSU student is associated with lower levels of narcissism. She needs to be skeptical of her findings because she did not have a random sample. She needs to be skeptical of her findings because she did not have random assignment. She can conclude that her sample is externally valid because it replicates previous research. She can conclude that being a SSU student causes narcissism to decrease.
In a previous practice assignment, you learned about a study in which volunteers (who were all around 30 years of age) from the Chicago area wore light sensors to measure their exposure to sunshine. It was found that those who experienced more daylight had lower body mass indexes (BMIs). The study was observational. It was not an experiment, so conclusions about cause and effect could not be made. Let's redesign the observational study described above into an experimental study.
In the Preview for this Chapter, we discussed a study by McGee and Shevlin (2009) demonstrating that an individual’s sense of humor had a significant effect on how the individual was perceived by others. In one part of the study, female college students were given brief descriptions of a potential romantic partner. The fictitious male was described positively and, for one group of participants, the description also said that he had a great sense of humor. Another group of female students read the same description except it now said that he has no sense of humor. After reading the description, each participant was asked to rate the attractiveness of the man on a seven-point scale from 1 (very unattractive) to 7 (very attractive) with a score of 4 indicating a neutral rating. a. The females who read the “great sense of humor” description gave the potential partner an average attractiveness score of M = 4.53 with a standard deviation of s = 1.04. If the sample consisted of n = 16…

a newspaper article claims that the average age for people who recieve food stamps is 35 years. You believe that the average age is less that that. You take a random sample of 100 people who recieve food stamps and find their average age to be 34.2 years. What conclusion can you make?
this is part 2 of a question. Although older Americans are most afraid of crime, it is young people who are more likely to be the actual victims of crime. It seems that older people are more cautious about the people with whom they associate. A national survey showed that 10% of all people ages 16-19 have been victims of crime.† At a high school, a random sample of n = 66 students (ages 16-19) showed that r = 11 had been victims of a crime. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer. Find a 90% confidence interval for the proportion of students in this school (ages 16-19) who have been victims of a crime. (Round your answer to three decimal places.) lower limit upper limit (c) How large a sample size should be used to be 95% sure that the sample proportion p̂ is within…

Dorinda is in second grade. She asks 6 of her classmates if they like to wear friendship bracelets. Four of her classmates said yes. Based on her findings, would it be reasonable to assume that about 2/3 of the pupils at her school (which has kindergarten through fifth grade) would also like to wear friendship bracelets? Why or why not?
