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…
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.
A psychologist is interested in whether hypnosis affects mood and emotion. 12 college students from the freshmen class are randomly sampled for an experiment. The experiment has two conditions which are given on different days. In condition 1, the students are hypnotized and then given a questionnaire which measures the levels of positive emotion. The higher the score indicates higher levels of positive emotion. In condition 2, the same students are given the questionnaire again, only this time they are not hypnotized but are in their normal state of consciousness. The following scores are obtained. Student 1 2 3 4 5 6 7 8 9 10 11 12 Condition 1 30 17 23 28 43 28 16 15 13 17 21 31 Condition 2 24 3 14 11 15 12 4 10 29 14 10 22 (hint: refer to "Week 8 quiz_ answer key and solution" document on Blackboard) The non-directional alternative (H1) hypothesis is _________. hypnosis…

A counseling psychologist hypothesizes that more perceived femininity predicts less perceptions of a traumatic event. Participants in a study are asked to rate the combat situation of female soldiers that recently returned from combat and suffered from depression. Participants rated the combat situation with respect to how traumatic they believe it was and assessed how feminine they perceived the female soldier to be. Higher scores indicate more trauma and femininity, respectively, on the ratings of the situation as traumatic and perceptions of being feminine. The data are below. What can the psychologist conclude with an α of 0.05?

Willerman et al. (1991) collected a sample of 40 right-handed Anglo introductory psychology students at a large southwestern university. Subjects took four subtests (Vocabulary, Similarities, Block Design, and Picture Completion) of the Wechsler Adult Intelligence Scale-Revised (1981). The researchers used Magnetic Resonance Imaging (MRI) to determine the brain size of the subjects. The research hypothesis was that brain size is correlated with IQ. The data are below: Participant 1 2 3 4 6 17 8 Which statistical test would you select: Pearson Correlation Ho: p = 0 H₁: p = 0 ◆ ◆ Enter the data above into and JAMOVI and use the correct statistical procedure to test the null hypothesis - answer the following questions: What is the coefficient that indicates the strength of the relationship? r ◆ = 0 What is the standard error?

The director of student services at Oxnard College is interested in whether women are less likely to attend orientation than men before they begin their coursework. A random sample of freshmen at Oxnard College were asked what their gender is and whether they attended orientation.

The authors of a paper describe an experiment to evaluate the effect of using a cell phone on reaction time. Subjects were asked to perform a simulated driving task while talking on a cell phone. While performing this task, occasional red and green lights flashed on the computer screen. If a green light flashed, subjects were to continue driving, but if a red light Flashed, subjects were to brake as quickly as possible. The reaction time (in msec) was recorded. The following summary statistics are based on a graph that appeared in the paper. n = 49 x = 530 S = 65 USE SALT (a) Construct a 95% confidence interval for u, the mean time to react to a red light while talking on a cell phone. (Round your answers to three decimal places.) Interpret a 95% confidence interval for μ, the mean time to react to a red light while talking on a cell phone. We are 95% confident that the mean time to react to a red light while talking on a cell phone is between these two values. There is a 95% chance…
A flextime program permits employees to design their own workweek to meet their personal needs. A firm starts a pilot flextime program to test its results. Nine random employees were given a questionnaire to measure their attitude toward their job before and after using a flextime program. The resulting attitude scores are displayed in the accompanying table. The higher the score, the more favorable the employee's attitude toward his or her work. Use a nonparametric test procedure to evaluate the success of the pilot program. Test using a = 0.05. E Click the icon to view the data table. ..... Set up the null and alternative hypotheses. Choose the correct answer below. O A. Ho: The probability distributions of the two populations are identical. H.: The before probability distribution is shifted to the left of the after probability distribution. - X Data Table O B. Hn: The before probability distribution is shifted to the left of the after probability distribution. H3: The probability…
Swearing is a common, almost reflexive, response to pain. Whether you knock your shin into the edge of a coffee table or smash your thumb with a hammer, most of us respond with a streak of obscenities. One question, however, is whether swearing has any effect on the amount of pain that you feel. To address this issue, Stephens, Atkins, and Kingston (2009) conducted an experiment comparing swearing with other responses to pain. In the study, participants were asked to place one hand in icy cold water for as long as they could bear the pain. Half of the participants were told to repeat their favorite swear word over and over for as long as their hands were in the water. The other half repeated a neutral word. The researchers recorded how long each participant was able to tolerate the ice water. After a brief rest, the two groups switched words and repeated the ice water plunge. Thus, all the participants experienced both conditions (swearing and neutral) with half swearing on their first…
