In a pattern recognition study, the participants were asked to examine a picture and see ifthey could recognize a word. The picture contained the word 'technology' written backwards.A total of 11 librarians and 13 designers succeeded in recognizing the word. The times taken(in seconds) for the successful participants recognized the word were as follows.LibrariansDesigners54 87 11 62 68 27 90 5769 34 27 51 29 45 42 48 74 31 30 3155189923a) Test the hypothesis that the variability of times taken for librarians exceeds the timestaken for designers at 5% level of significance.b) Construct a 95% confidence interval for the mean of times taken by librarians. Interpretthe interval obtained.

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…

Hello, May I get help on this VERY SOON please? I’m extremely confused and a clear explanation would be helpful! Thank you!
A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…
