- Diana tested the effect of number of items on short-term memory in dolphins. She randomly presented visual arrays with 1, 2, 3, 5, 8, 13, 21 items for five minutes. She asked 3 dolphins to remember the items. She then presented a new array with old and new items. The dolphins responded by touching the items with their tails. She hypothesized that Dolphins could remember 3 items accurately, but not more than that. What would be the family wise error rate if she conducted the maximum number of pairwise comparisons give an pairwise alpha of 0.01?You have two groups of researchers getting data on a new drug for Alzheimer’s patients with working memory loss. Both researchers give the same memory task performed using the Wisconsin Card Sorting Task and count the number of correct answers from 15 patients each.The results of Researcher A are: 60, 62, 70, 55, 78, 53, 78, 53, 70, 66, 62, 79, 51, 65, 69The results of Researcher B are: 68, 75, 71, 65, 58, 74, 68, 72, 60, 59, 72, 65, 70, 72, 69Which set of scores has a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.Assortative Mating: Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studying this topic collected data on eye colors of 208 Scandinavian men and their female partners. The table below summarizes the results (rows represent male eye color while columns represent female eye color). For simplicity, we only include heterosexual relationships in this exercise. (Round any numerical answers to 4 decimal places if possible.)

- Let's assume that there are 500 people in a population. The researcher has access to all 500 participants, and sends a questionnaire that is accessed by a hyperlink. Of the 500 possible subjects, 485 complete it. Does this mean that the results generated from this study will be highly-accurate? What might cause the study to be unreliable?Help!!Help please. I am extremely confused and do not understand this! Can I get help with all parts please
- You are conducting a compliance audit of the training department where you work at BeyondUs. You view the statistics for employees completing their training. Here are the daily counts of completed BeyondUs ethics compliance training over a recent 7 day period: 10, 38 , 4, 71, 2, 1, 9 Use an 11 node grid with a maximum of 25 and a minimum of 8 average trainings per day. What is the expected number of trainings less than the most plausible average number of trainings per day? Select one: а. 18 b. 19 С. 20 d. 15PLEASE HELPDuring the get-together for Gerdau developers, 17 employees sat around a large round table. Each of the collaborators received a paper that said if he should say only the truth or only a lie. During the dynamic performed, each one should say which colleagues were lying and which were telling the truth. At the end of the game, all employees who were participating said: "The two people next to me are liars". At a minimum, how many employees received the paper saying to tell only the truth?

She randomly presented visual arrays with 1, 2, 3, 5, 8, 13, 21 items for five minutes. She asked 3 dolphins to remember the items. She then presented a new array with old and new items. The dolphins responded by touching the items with their tails. She hypothesized that Dolphins could remember 3 items accurately, but not more than that. How many pairwise comparisons should she do according to the recommended guideline?1) For each of the following pairs of variables, is there likely to be a positive association, a negative association or no association? Briefly explain your reasoning. (a) Amount of alcohol consumed and performance on a test of coordination. (CHOOSE ONE) i) There is likely to be a positive association. As alcohol consumption increases, performance on a test of coordination will tend to increase. ii) There is likely to be a negative association. As alcohol consumption increases, performance on a test of coordination will tend to decrease. iii) No association would be expected between amount of alcohol consumed and performance on a test of coordination. (b) Height and grade point average for university students. i) There is likely to be a positive association. As height increases, grade point average for university students will tend to increase.There is likely to be a negative association. As height increases, grade point average for university students will tend to decrease.…
