They will then measure the levels of caffeine in these individuals’ systems at 10am, 12am, 2pm, 4pm, 6pm and 8pm. They want to have at least 20 observations per group. How many separate/distinct groups of participants are needed if they want to conduct this experiment using a mixed-measures ANOVA? 18 6 20 3A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 18 offspring birthed.They then observe that 10 are female.Use a sign test to test the indicated hypothesis.What is the value of "significance"
- Dr. Moas is interested in examining how environmental cues affect memory. She asks 15 students to study 10 obscure words for a vocabulary exam. All students take the final vocabulary exam in Classroom A. She randomly assigns participants to one of three locations to study for the exam: the same classroom (Classroom A), a different classroom (Classroom B), or a completely separate location, the school gym. Then, she records the number of vocabulary words that each student correctly defines on the exam. The data is as follows: Participant Study Location Vocabulary Words Answered Correctly 1 Same Classroom 9 2 Same Classroom 8 3 Same Classroom 10 4 Same Classroom 8 5 Same Classroom 9 6 Different Classroom 9 7 Different Classroom 8 8 Different Classroom 7 9 Different Classroom 8 10 Different Classroom 7 11 School Gym 6 12 School Gym 7 13 School Gym 5 14 School Gym 6…Dr. Moas is interested in examining how environmental cues affect memory.

Researchers recruited 126 female participants and assigned each to one of the two mannequin styles (head/headless). Participants were asked to imagine that they wanted to buy a new dress and told to go to a named store to make their purchase. They then viewed the dress displayed on a mannequin (head or headless) and were asked whether or not they would buy the dress. Of the 63 participants viewing the dress displayed on a mannequin with a head, 18 indicated that they would buy the dress, while only 10 of the 63 participants viewing the headless mannequin indicated that they would buy the dress. SOLVE : Are the conditions met to carry out the desired hypothesis test? One observed count of a success, namely the women who would buy a dress after seeing it on a headless mannequin, is ten,…
- A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

The club have identified 12 potential camera locations within the stadium. They have also identified 25 stadium areas which may require camera coverage during the pre-game, game and post-game activities. The following table indicates each camera location and the stadium areas the camera can cover: Camera Location 1 2 3 4 5 6 7 8 9 10 11 12 Stadium Areas 1,3,4,6,7 8,4,7,12 2,5,9,11,13 1,2,18,19,21 3,6,10,12,14 8,14,15,16,17 18,21,24,25 2,10,16,23 1,6,11 20,22,24,25 2,4,6,8 1,6,12,17 Bayern Munich executives are concerned about the costs for the production. Consequently, they have set an objective of minimizing the number of camera locations. In seeking this objective they want at least one camera to be available to cover each stadium area. Camera location 9 is the "blimp," and executives have decided that the blimp will be used because of viewer expectation and fascination with the shots from…Throughout the world, women are targets of harassment, discrimination, violence, and evenmurder due to perceptions of their clothing choices. Some women are targeted because theydress to religious and some women are targeted because they do not dress religious enough. Aresearcher was interested in determining if countries that had more restrictions on how womendress (i.e., how many laws regulate women’s clothing choices?) also had more women reportingsocial hostility from others (e.g., discrimination, abuse, violence). What statistical test should beused to determine if there is a relationship between number of women’s clothing regulations andthe number of reports of social hostility? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B. What would be the appropriate statistical test? Explain your rationale.
- In a series of studies, Sebastian Deri and his colleagues (2017) asked multiple groups about the number of friend groups they had and how often they attended different social events. They then asked participants how they thought their own numbers compared to other people's: Did participants see themselves as less social, the same as, or more social than others? In the first study, the researchers reported that: "Three hundred four participants from Amazon's Mechanical Turk (150 women; Mage = 37.1; 78% White, 10% Black, and 6% Asian) completed a survey in exchange for modest payment" (p. 860). What do the researchers mean by "Amazon's Mechanical Turk" with respect to their sample of participants? O A. An archival data set that already exists and from which researchers can use data O B. An online tool that researchers can use to recruit people to participate in research in exchange for a small payment O C.

For each permit issued, the department inspects the result of the project and gives a "pass" or "fail" rating. A failed project must be re-inspected until it receives a pass rating. The department had been frustrated by the high cost of re-inspection rate and decided to publish the inspection records of all contractors on the web. It was hoped that public access to the records would lower the re-inspection rate. A year after the web access was made public, two samples of records were randomly selected. One sample was selected from the pool of records before web publication and one after. The proportion of projects that passed on the first inspected was noted for each sample. The results are summarized below. No Public Web Access nį = 500, ĝ1 = 0.67 Public Web Access n2 = 100, p2 = 0.80 A test, at a 0.10 level of significance, is to be conducted as to whether…
