3. How Fast Can You List Your Favorite Things? If you are asked to make a list of objects in a certain category, how fast you can list them follows a predictable pattern. For example, if you try to name as many vegetables as you can, you’ll probably think of several right away- for example, carrots, peas, beans, corn, and so on. Then after a pause you might think of ones you eat less frequently-perhaps zucchini, eggplant, and asparagus. Finally, a few more ex- otic vegetables might come to mind-artichokes, jicama, bok choy, and the like. A psycholo- gist performs this experiment on a number of subjects. The table below gives the average number of vegetables that the subjects named by a given number of seconds. (a) Find the cubic polynomial that best fits the data. (b) Draw a graph of the polynomial from part (a) together with a scatter plot of the data. (c) Use your result from part (b) to estimate the number of vegetables that subjects would be able to name in 40 s. (d) According to the model, how long (to the nearest 0.1 s) would it take a person to name five vegetables?

What percentage of data would you predict would be between 25 and 50 and what percentage would you predict would be more than 50 miles? Use the Week 4 spreadsheet again to find the percentage of the data set we expect to have values between 25 and 50 as well as for more than 50. Now determine the percentage of data points in the dataset that fall within each of these ranges, using same strategy as above for counting data points in the data set. How do each of these compare with your prediction and why is there a difference? Predicted percentage between 25 and 50: ________________________ Actual percentage: Predicted percentage more than 50 miles: Actual percentage: ___________________________________________ Comparison ____________________________________________________ Why? __________________________________________________________ Drive: 44 20 88 6 71 42 76 63 61 63 84 28 55 33 88 80 86 83 5 85 25 25 54 54 81 73 29 76 78…
Marco shows you the following chart to help him argue that while his division’s sales numbers aren’t as high as those of the other divisions, he’s actually not that far behind them, when you look at the data visually. How is Marco using a chart to lie to you? What would a more accurate representation of Marco’s performance look like?
Packages arrive at the stockroom and are delivered on carts to offices and laboratories by student employees. The carts and packages are various sizes and shapes. The students are paid according to the carts used. There are 6 carts and the pay for their use is Product C1: $1 Product C2: $3 Product C3: $2 Product C4: $4 Product C5: $1 Product C6: $2 On a particular day, 9 packages arrive, and they can be delivered using the 6 carts as follows: C1 can be used for packages P1, P3, P4 and p7. C2 can be used for packages P2, P5, and P6, and p8. C3 can be used for packages P1, P2, P5, P6, and P7. C4 can be used for packages P3, P6, and P7 and 9. C5 can be used for packages P2, P4 and p8. C6 can be used for packages P1, P2 and P3 The stockroom manager wants the packages delivered at minimum cost. Using minimization techniques described in this unit, present a systematic procedure for finding the minimum cost solution. Use Petrik Method

Attempt 7 Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000. To investigate such claims, one study used a special device to record the conversations of male and female university students over a four-day period. From these recordings, the daily word count of the 20 men in the study was determined. The table contains their daily word counts. 28,408 10,084 15,931 21,688 37,786 10,575 12,880 11,071 17,799 13,182 8,918 6,495 8,153 7,015 4,429 10,054 3,998 12,639 10,974 5.255 To access the complete data set, click the link for your preferred software format: Excel Minitab JMP SPSS TI R Mac-TXT PC-TXT CSV Crunchlt!
