Solve the prior knowledge problems CSCONCEPTSThe following key concepts will be addressed in this chapter:Organizing, representing, analysing and interpreting data, and utilizing differentstatistical tools, facilitate prediction and drawing of conclusions.Different statistical techniques require justification and the identification of theirlimitations and validity.Approximation in data can approach the truth but may not always achieve it.Correlation and regression are powerful tools for identifying patterns.PRIOR KNOWLEDGEBefore starting this chapter, you should already be able to complete the following:1 For the data 1, 2, 2, 5, 6, 6, 6, 10, find:athe meanthe mode-81с2 For the straight line with equation y = 1.5x+7, statea the gradientbthe coordinates of the point where the line crosses the y axis.OPE.E & bowodede expornow He tadi atasgeitubong niTOOLKIT: Probl Soter Activityishlodlibas slam3563179uslugoat the graphs in Figure 6.1 and discuss what message they are trying to convey.

In a classic study in the are of problem solving, Katona (1940) compared the effectiveness of two methods of instruction. One group of participants was shown the exact, step-by-step procedure for solving a problem and was required to memorize the solution. Participants in a second group were encouraged to study the problem and find the solution of their own. They were given helpful hints and clues, but the exact solution was never explained. The study included the problem in the following figure showing a pattern of five squares made of matchsticks. The problem is to change the pattern into exactly four squares by moving only thee matches. (All matches must be used, non can be removed, and all the squares must be the same size.) After 3 weeks, both groups returned to be tested again. The two groups did equally well on the matchstick problem they had learned earlier. But when they were given new problems (similar to the matchstick problem), the memorization group had much lower scores…

(Devore Section 2.3 #30) A friend of mine is giving a dinner party. His current wine supply includes 8 bottles of zinfandel, 10 of merlot, and 12 of cabernet (he only drinks red wine), all from different wineries. (a) If he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? (b) If 6 bottles of wine are to be randomly selected from the 30 for serving, how many ways are there to do this? (c) If 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? (d) If 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (e) If 6 bottles are randomly selected, what is the probability that all of them are the same variety?
Can I have detailed explanation for parts (b) & (c) of the following question? Thank you!
Solve the given problem completely. Show your solution. In a dance crew with 32 members, 9 are are part of unit A, 10 are in unit B, and 6 performs solo. 3 members of unit A are also in unit B. Two solo performers are also in unit A:. 2 members of unit B are also solo performers. Only 1 member of the crew is part of all units. How many crew members do not belong in unit A nor B, nor soloists?
Provide numerical answers to each of the following. Show your work clearly. (a) How many ways are there for a class of six kids to line up for recess? (b) The first child and last child play important roles in the line. Two of your students, Blork and Zonk, are terrible and horribly irresponsible. Blork cannot be trusted to be first in the line, while Zonk cannot be trusted to be last. If the line forms randomly, what is the probability that Blork will be first OR Zonk will be last? Leave your answer as a fraction.
To increase the response rate to mail questionnaires, researchers sometimes give monetary incentives as a reward to respondents for their cooperation. Could there be situations where a relatively large reward — e.g., rewarding the respondent with $30 for answering 10 short questionnaire questions — might end up resulting in biased answers from the respondents? If so, give a real or hypothetical example of such an occasion.
