Dr. S. Oberman has the research hypothesis that drivers who have consumed one drink perform slightly better (score higher on a driving test) than drivers who have had no alcohol. She believes that one drink makes them relaxed and less nervous. She tests this by having subjects take a standard driving test. It is known that completely sober, college-student drivers score an average of 75 on this test, where high scores indicate better driving.Dr. S. Oberman's null hypothesis is: [note: μ₀ means mu, the population mean according to the null hypothesis]- ○ μ₀ is equal to 0- ○ μ₀ is less than 0- ○ μ₀ is not known, nor can it be known- ○ μ₀ is equal to (or less than) 75- ○ μ₀ is greater than 75

Given the claim: The drivers who have consumed one drink are actually slightly better than drivers who have had no alcohol. Dr. S. Oberman's null hypothesis is: H0: μ0 is equal to or (less than) 75 That is, The drivers who have consumed one drink score less than or equal to 75 on average.

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

I want to know if being an athlete or not would change the resuls to the donut vs. bagel study. I have a group of athletes and non-athletes and for one month I have half of the athletes eat donuts, the other half bagels and I have half the non-athletes eat donuts, the other half bagels and measure their kindness. What analysis do I use?
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 social worker is interested in examining how people who have higher levels of psychological resiliency respond after a natural disaster. She obtained anxiety scores, which were measured on a scale of 1–12 with higher numbers meaning more anxiety, from eight individuals who had experienced a natural disaster. She collected these scores 3 weeks after the disaster (M=7.13, s=2.03) and 6 months after the disaster (M=3.5, s=1.6). She expected that the anxiety scores at 6 months would be much lower than at 3 weeks. If sD = 1.30 and you use a two-tailed test with an alpha of .05, is there a difference? Perform the 4 steps of hypothesis testing. Anxiety at 3 weeks Anxiety at 6 months: 9 610 55 24…
A group of college students believes that herbal tea has remarkable restorative powers. To test their theory, they make weekly visits to a local nursing home, visiting with residents, talking with them, and serving them herbal tea. After several months, many of the residents are more cheerful and healthy. (a) Which of the following may be correctly concluded from this study? A. Herbal tea does improve one's emotional state, at least for the residents of nursing homes. B. The results of the study are not convincing because the effect of herbal tea is confounded with several other factors. C. The results of the study are not convincing because only a local nursing home was used and only for a few months. D. There is some evidence that herbal tea may improve one's emotional state. The results would be completely convincing if a scientist had conducted the study rather than a group of college students. (b) The lurking variable in this experiment is A. the emotional state of the residents.…
You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. However, past research indicates that about 30% of people who get the flu experience nausea, and you believe that the percentage of those who experience nausea while having the flu and taking Tamiflu will be greater than 30%, which would indicate that nausea is a side effect of Tamiflu.If you are going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses? H0: ? p = p ≠ p < p > p ≤ p ≥ μ = μ ≠ μ < μ > μ ≤ μ ≥ H1: ? p = p ≠ p < p > p ≤ p ≥ μ = μ ≠ μ < μ > μ ≤ μ ≥ What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed
Amit Almor, a psychology researcher at the University of South Carolina, conducted a series of experiments on conversation and attention level. He found that subjects were four times more distracted while preparing to speak or speaking than when they were listening. This research has many implications, including those for the issue of using cell phones while driving. You decide to explore this issue by having three different groups try tracking a fast-moving target on a computer screen. The first group is preparing to speak, the second group is speaking, and the third group is listening to a conversation. The sample mean and sum of squares of the scores for each of the three groups are presented in the following table. Group Sample Mean Sum of Squares Preparing to speak 98.3 7,2810.0900 Speaking 101.5 6,6156.8100 Listening 103.2 70,277.7600 After collecting the data, you analyze the data using an ANOVA.

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.
The medical researcher is comparing two treatments for lowering cholesterol: diet and meds. The researcher wants to see if the patients who receive the recommendation to change their diet have more success lowering cholesterol compared to a prescription of meds. A random sample of some patients who received the recommendation to change their diet and others who were prescribed meds was taken. The results of how many did or did not lower their cholesterol are shown below: Data on Diet vs. Meds for Weight Loss Diet Meds Yes 424 502 No 255 320 What can be concluded at the = 0.05 level of significance?

How much customers buy is a direct result of how much time they spend in the store. A study of average shopping times in a large national houseware store gave the following information (Source: Why We Buy: The Science of Shopping by P. Underhill). Women with female companion: 8.3 min.Women with male companion: 4.5 min. Stores that sell mainly to women should figure out a way to engage the interest of men! Perhaps comfortable seats and a big TV with sports programs. Suppose such an entertainment center was installed and you now wish to challenge the claim that a woman with a male friend spends only 4.5 minutes shopping in a houseware store.
