Twelve chairs are to be painted. The available colors are Red, Blue, Green, and Yellow, and every chair must be painted with one color. Assuming that all coloring schemes are equally likely, what is the probability that one color is not used and there are at least two chairs of every other color ? (The answer is 0.25) Can anyone explain to me why ?

The distribution of M&M colors is 24% blue, 20% orange, 16% green, 14% yellow, 13% red, and 13% brown. You have a small bag of M&M's and count the colors. Your bag has 9 blue, 9 orange, 4 green, 12 yellow, 3 red, and 6 brown M&M's. Before you begin, how many M&M's do you need in your sample (minimum) to be able to do this test? Remember, your assumption for chi-square is that every expected frequency has at least...

Milk Chocolate M&M’s come in 6 colors; blue, orange, green, yellow, red, and brown. 1. Choose your favorite color of M&M’s you will be working with for this project. State the color and give the counts below. Color of choice: Number of M&M's in your color: Total number of M&M's: Proportion of M&M's in your color: 2. Construct a 95% confidence interval for the proportion of M&M’s one can expect to find in the color of your choice. 3. Give...

(a)Jordan Almonds have a colored candy coating with colors: Yellow, Green, Purple, Pink, White, and Blue. In a single bag the frequencies were 18, 24, 26, 17, 16, 28, resp. Are the frequencies consistent with an equal distribution of colors? (b)A second bag had frequencies 17, 26, 15, 14, 16, and 22, resp. Is this bag also consistent with equal distribution of colors? A third bag had frequencies 11, 27, 17, 22, 19, and 21, resp. Can the bags be...

Chocolates N&N come in 3 colors: blue, red and yellow. A chocolate bag should, on average, be filled with 40% of blue, 40% of red and 20% of yellow. The supervisor test the machine by taking a sample of bags. He counts 85 blue, 106 red, and 43 yellow in this sample. α = 0.05 a) What are the null and alternative hypothesis? Define any necessary variables. b) What is the test statistic? c) What is the critical value or...

(5 pts) Suppose that the five standard Skittles colors (red, orange, yellow, green, purple) occur with equal relative frequency. Use the random digits below to simulate the colors of 4 randomly selected Skittles. Continue to do this until you have generated 12 such samples of 4 Skittles. Use the results of these simulations to approximate that probability that a sample of 4 Skittles will contain at least two Skittles of the same color. 28491 06339 65216 31007 92314 50271 82943...
