The characteristics of check teeth (e.g., molars) can provide anthropologists with information on the dietary habits of extinct mammals. The check teeth of an extinct primate species was the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). A total of 18 check teeth extracted from skulls discovered in western Wyoming were analyzed. Each tooth was classified according to degree of wear (unworn, slight, light-moderate, moderate, moderate-heavy, or heavy). The 18 measurements are listed here.

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

A random sample of 395 people were surveyed and each person was asked to report the highest education level they obtained .The data that resulted from the survey is summarized in the following table: High School Bachelors Masters PhD. Female 60 54 46 41 Male 40 44 53 57 Question: Are gender and education level dependent at 5percent level of significance ?

Given this information, can we determine if there is an association between sex and academic performance? (Choose the one best answer). Group of answer choices Yes, female students have a lower rate of poor academic performance therefore poor academic performance is associated with being a female student. No, male students only have a slightly higher prevalence of poor academic performance compared to female students and therefore there is no association between poor performance and gender. Yes, male students have a higher rate of poor academic performance therefore poor academic performance is associated with being a male student. No, the prevalence values alone cannot be used to assess an association between…arrow_forward
- The article “Developing a Tool to Measure the Factors Influencing Nurses' Enjoyment of Nursing” (L. Wilkes, M. Doull, et al., Journal of Clinical Nursing, 2016:1854–1860) reports that in a sample of 124 nurses, 54 said that a busy workload had a positive effect on their enjoyment of their job. Can you conclude that less than 45% of nurses feel that a busy workload has a positive effect on their enjoyment of their job?arrow_forwardIn a pilot study, participants responded to a survey on sexual attitudes (the BSAS). BSAS scores were median-split and participants were assigned to a low BSAS (Sexually Conservative coded a 1) or a high BSAS (Sexually Progressive, coded a 2) group. Participants then read a scenario which described a woman with either sexually conservative or progressive attitudes who is sexually assaulted on a date with a man. Finally, participants responded to a scale with measured the participant's personal similarity to the target. The item responses to this scale were combined into a composite score.

- Siegel (1990) found that elderly people who owned dogs were less likely to pay visits to their doctors after upsetting events than were those who did not own pets. Similarly, consider the following hypothetical data. A sample of elderly dog owners is compared to a similar group (in terms of age and health) who do not own dogs. The researcher records the number of doctor visits during the past year for each person. The data are as follows. Control group:10,8,7,9,13,7,6,12 Dog owners: 7, 4,9,3,7 a. In words and symbols, state the null hypothesis and the alternative hypothesis using a two-tailed test.

Two different groups, each with 28 dieters, are chosen for the study. Group A is required to follow a specific diet and exercise regimen, and also take a 500-mg supplement of calcium each day. Group B is required to follow the same diet and exercise regimen, but with no supplemental calcium. After six months on the program, the members of Group A had lost a mean of 15.2 pounds with a standard deviation of 2.5 pounds. The members of Group B had lost a mean of 12.3 pounds with a standard deviation of 1.9 pounds during the same time period. Assume that the population variances are not the same. Construct a 95% confidence interval to estimate the true difference between the mean amounts of weight lost by dieters who supplement with calcium and those who do not. Let Population 1 be the amount of weight lost by Group A, who took a 500-mg supplement of calcium each day, and let Population 2 be the…arrow_forwardResearchers studied a group of 30 “self-designated worriers” (i.e. individuals who reported spending at least 10% of the day worrying) and who were over the age of 70 (mean age of 78.1). The researcher randomly assigned the worriers into three groups. For the next four weeks, each group would experience a different approach to handling worry. One group engaged in a worry-focus discussion group. The second group members enjoyed individual therapy. The third group went for daily walks in the park. Data was collected, analyzed, and interpreted. 41. The above design utilizes what type of group assignment technique: a. mixed factorial with combined assignment (mixed combo). b. repeated measures. c. nonequivalent groups. d. independent groups. e. quota sampling.arrow_forward
