When MapReduce is executed, data are first dividedup into manageable subsets and distributed todifferent computers for storing and processing.Then, the answers from each of those computersare combined into one answer. Notice that the firstsentence clarifies that processing (and storing) isdone by "different computers." The second sentencementions these different computers again, this timereferring to them as "those computers". What termis often used to refer to each one of those differentindividual computers? (hint: The general term isoften followed by a number as a means ofidentifying specific computers in the programmingmodel.)ClusterProcessorO ClientO Node

The data file includes the text of three books of the Bible (Joshua, Jonah and Philippians) using the ESV translation. While these are all great books, our only interest for this project is how often each letter is used. 1) In the Word file containing the Biblical text, use the “Find” feature to identify how many times each letter occurs (i.e. the letter’s frequency). Create an Excel spreadsheet to display the number of occurrences of each letter in the English alphabet. Here is the amount of occurences I found for each letter using the find feature A=1810 B=323 C=442 D=1097 E=2845 F=609 G=416 H=1689 I=1381 J=134 K=143 L=935 M=586 N=1503 O=2237 P=379 Q=5 R=1362 S=1407 T=2235 U=703 V=257 W=513 X=17 Z=6 2) In the Excel spreadsheet, sum your frequencies to compute the total number of letters in the 3 books (this is n). a) In your spreadsheet, use the formula to compute the sample proportion of each letter’s appearances relative to total number of letters (i.e. find the relative…
In 1974, Loftus and Palmer conducted a classic study demonstrating how the language used to ask a question can influence eyewitness memory. In the study, college students watched a film of an automobile accident and then were asked questions about what they saw. One group was asked, “About how fast were the cars going when they smashed into each other?” Another group was asked the same question except the verb was changed to “hit” instead of “smashed into.” The “smashed into” the group reported significantly higher estimates of speed than the “hit” group. Suppose a researcher repeats this study with a sample of today’s college students and obtains the following results. Estimated SpeedSmashed Into Hitn = 16 n = 16M = 40.8 M = 34.0SS = 510 SS = 414 For this problem, complete the four stages of hypothesis testing to determine whether the assumption of homogeneity of variance is met. (Note: This problem is NOT asking you to conduct an independent-samples t-test.) Use a nondirectional…
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?
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…

Need help with parts (a) to (g) on this homework problem. Make sure the answers are lengthy. Also, make sure your handwriting is neat and readable. Below the homework problem is a screenshot of an excel spreadsheet with data for this problem. If there is one thing engineers like, it is a good pizza that is delivered in a timelymanner. A particular pizza chain is thinking about offering a guarantee of “lessthan 30 minutes, or it’s free” on all of its deliveries. If the pizza business can pullthis off, they will impress customers across the nation, but having to walk thispromise back would be devastating to the reputation of the business. However,the CEO will not green light this policy if it means taking a substantial hitto profits. Accounting has run some numbers, and they have determined thatthe business can only miss 5% of all deliveries before the costs of the misseddeliveries begin to impact profitability. The CEO agrees to a pilot test. 120drivers time their deliveries with a…
