People tend to evaluate the quality of their lives to others around them. In a demonstrationof this phenomenon, Frieswijk, Buunk, Steverink, and Slaets (2004) conducted interviewswith frail elderly people. In the interview, each person was compared with fictitious otherswho were worse off. After the interviews, the elderly people reported more satisfaction withtheir own lives. Following are hypothetical data similar to those obtained in the researchstudy. The scores are measures of a life-satisfaction scale for a sample of n=9 elderlypeople who completed the interview. Assume that the average score on this scale is u=20.What is your computed t? Use a one-tailed test with a=0.05. The life satisfaction scores are18, 23, 24, 22, 19, 27, 23, 26, 25. Note: S2-sS (sum of squares)÷df (degrees of freedom)Answer:

Here population mean is 20 and samples are 9. We will use t-test at 5% level of significance.

A researcher uses a matched-samples design to investigate whether single people who own pets are generally happier than singles without pets. A mood inventory questionnaire is administered to a group of 20- to 29-year-old non-pet owners and a similar age group of pet owners. The pet owners are matched one to one with the non-pet owners for income, number of close friendships, and general health. The data are as follows: Matched pair Non-pet Owner Pet owner A 10 15 B 9 9 C 11 10 D 11 19 E 5 17 F 9 15 1. Is there a significant difference in the mood scores for non-pet owners versus pet owners? 2.What is the appropriate statistical tool? 3. t-value? 4. p-value? 5. Interpret the results.
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?

Empathy among police officers influences how they interact with citizens and the likelihood that they receive complaints. Gender differences in levels of empathy in the general population are not large but male and female officers have been shown to have different interaction styles with the public; this may be due to the different empathy levels. After sampling officers and measuring their levels of empathy you find the following data. Males Females n = 6 n = 9 M = 31 M = 45 SS = 490 SS = 680 If you were going to make gender comparisons like this, which option would be the correct choice? Write A or B in the box. [a] Option A. Independent-measures t-test Option B. Repeated-measures t-test
In a study examining the relation of math ability to the belief that math ability was innate, the belief was considered the predictor variable. The researcher hopes to find a correlation between the participants’ math ability and their belief that math ability is innate. The scores for the three participants are shown below. The group that believed that math is NOT innate scored 66, 70, 50. The group that believed that math IS innate scored 7, 4,10. what are the mean and SD for each group?
An online dating company wants to investigate perceptions of the services they offer. Two independent research companies collect data and ask several questions of a sample of individuals who identify as "single." Specifically, they want to determine at a 5% significance level if more than half of single people answer "yes" to the question, "Do you think that online dating is right for you?" The results for each researcher appear in the following table. Company A Company B P-value = 0.021 P-value = 0.063 "At the 5% significance level, the data provide convincing evidence that more than half of single people believe that online dating is right for them." "At the 5% significance level, the data do not provide convincing evidence that more than half of single people believe that online dating is right for them." Part A: Identify at least two reasons why the companies came up with different P-values. Part B: A researcher at Company B revisits the analysis and instead concludes the…
Seattle Grace Medical Center. As part of a long-term study of individuals 65 years of age or older, doctors at the Seattle Grace Medical Center in Washington state investigated the relationship between state of residence and depression. A sample of 60 individuals, all in reasonably good health, was selected; 20 individuals were residents of Texas, 20 were residents of Washington state, and 20 were residents of South Carolina. Each of the individuals sampled was given a standardized test to measure depression. The data collected follow; higher test scores indicate higher levels of depression. These data are contained in the attached data file SeattleGrace1. A second part of the study considered the relationship between state of residence and depression for individuals 65 years of age or older who had a chronic health condition such as diabetes and/or high blood pressure. A sample of 60 individuals with such conditions was identified. Again, 20 were residents of Texas, 20 were residents…
A marketing firm is doing research for an internet-based company. It wants to appeal to the age group of people who spend the most money online. The company wants to know if there is a difference in the mean amount of money people spend per morith on Internet purchases depending on their age bracket.
