I then repeated steps 1-9 using alcohol as my solvent, instead of the 1% salt solution. Data Observations 1. I predict the components I expect to see from each candy color will be watered down, mixed and dissolved pigments of each of the candy colors on the strip of paper. 2. 1% Saltwater Solution: Color Length Traveled (in centimeters) Yellow 6 cm Orange 5 cm Red 4 cm Purple 4.5 cm Green 0 cm (No Travel) Alcohol: Color Length Traveled (in centimeters) Yellow 2  ½ cm Orange 1  ½ cm Red 1  ½ cm Purple 1  ½ cm Green 2  ½ cm 3. Observations: a. It was hard to outline and cut the 2 paper strips to their exact measurements. b. It was hard to place the water equally distant from each other. c. The color from the candies dissolved into the water and disappeared from half of each of the candies. d. The colors began to fade and dissolve from the strip of paper. Using the salt solution, the only colors visible were yellow, orange, green and red. These colors were mixed, meaning there’s more of a lime and turquoise within the colors. e.

The saltwater solution worked better and had more effect on each of the colors on the strip of paper than the alcohol solution because the colors beganShow MoreRelatedOperations Management23559 Words   |  95 Pages000 320,000 $ 500,000 -150,000 320,000 Supplement 1-50 1- Maximax Solution STATES OF NATURE Good Foreign Poor Foreign Competitive Conditions DECISION Expand Maintain status quo Sell now Expand: Status quo: Sell: Competitive Conditions $ 800,000 1,300,000 320,000 $800,000 1,300,000 320,000 $ 500,000 -150,000 320,000 ↠ Maximum Decision: Maintain status quo Supplement 1-51 1- Maximin Solution STATES OF NATURE Good Foreign Poor Foreign Competitive Conditions DECISIONRead More_x000C_Introduction to Statistics and Data Analysis355457 Words   |  1422 Pagesstatistical methods are employed in reasonable and appropriate ways.
