3 pts.  Test their claim that the true proportion of yellow M&Ms® candies is 0.14 at the 0.05 significance level.

The initial mass of the gum was 9.8 grams and by the tenth trial it was at 5.19 grams; therefore, the mass started dropping at a rate of 0.5 grams to dropping only 0.05 grams every time the mass was recorded. From further observations, the more the gum was chewed the less taste there was and the sugar in the gum was responsible for the taste because towards the end of the experiment when the taste was almost gone, the mass of the gum went from seriously dropping to only dropping 0.05 grams every time the mass was recorded; also, the gum tasted a lot better in the beginning than it did in the end. Each student performed 25 trials (625 chews) to get more accurate data, implying that the more we did the less sugar content was left in the gum. I also observed that the more chewing we did the less percentage error we would have in comparison from our control groups’ percentage. Lastly, the existence curve shows how the mass drops plenty until most of the sugar was extracted and the data

Statistical analysis was performed with results as follows: the mean, or average number of candies per bag, was 55.648. The standard deviation, a measure of variance, was 2.8689. This means that the number of candies per bag can vary up to three candies. A histogram, a graph showing how the frequency of the data was distributed, was done to determine the characteristics of the data. The histogram appeared to be skewed to the left (negatively skewed). This means the data was not uniform.

The purpose of this experiment was to test multiple brands of popcorn under the same setting in order to conclude which one statistically popped the most kernels. I tested the butter flavor of Orville Redenbacher, Wal-mart’s Great Value brand, and Pop Weavers. The different bags of popcorn were popped in the same microwave for the same amount of time, 3 minutes and 15 seconds. Then, the popped corn was counted, as well as the un-popped kernels, in order to determine a ratio, and then I recorded the results in the data table. I repeated these steps two more times for a total of 3 trails for each brand. Then I compared the ratios of all the bags to determine which brand yielded the most popped corn. The statistical technique used to evaluate the data was to find a ratio between the number of kernels in the bottom of the bowl and the number of popped kernels. To find this, I divided the number of the actual popped corns by the total number of kernels left in the bottom of the bowl. The ratios and percent were then compared. Once all my results were in the data table, I averaged the 3 trials for each brand of popcorn.

Skittles are a hard shelled, fruit flavored candy loved by many today. Skittles first came into existence in Britain in 1974. They were introduced to the United States in 1979 but weren’t actually produced until 1982 where they are now a product of Wrigley. The Skittles catchphrase, “Taste the Rainbow” was came about in 1994. The Skittles Company has a variety of flavors from Sour Skittles, released in 2000; Bubble Gum Skittles, released in 2004; and Smoothie Fruit Mix, released in 2005. The Original Skittles consist of a strawberry flavor, an orange flavor, a lemon flavor, a green apple flavor, and a grape flavor. According to Wrigley, Skittles colors/flavors are all evenly distributed in each of their packs. So our question in hand was, is this claim actually true and if so, is the ratio of flavors in the regular sized (2.17 oz.) Skittles packs the same as the Fun Sized packs of Skittles? We chose do experiment with this because collectively as a group, we all love Skittles and from our understanding we initially assumed prior to conducting the experiment that Skittles had an equal number of flavors in each pack. There are five flavors in a pack, so that means that each pack should have 20% of each flavor. We decided that our null hypothesis would be H0:

In previous studies, Frank and Byram’s article suggest that taste and smell interactions are dependent on taste and odor. In their experiments, they gave subjects strawberry

In this lab, M&Ms and Smarties will be compared in five different ways: mass, shell solubility, volume, density, and nutrition facts. For each comparison 10 Smarties will be used and 10 M&Ms will be used. This is to ensure that the results are more accurate, as each piece of candy is not the same size, weight etc… A total of 50

Part 1 The way people perceive taste is impacted by a number of factors. These include, but are not limited to, age, weight, hormones, sickness and disease, smoking, and diet. Diet is the factor that this paper focuses on. Diet is impacted by the way people taste in that people are used to eating a certain amount of additives and preservatives. Some eat a very low amount, while for others, everything they eat contains additives and preservatives. There is a large range, but this paper will be focusing on two sides: people who eat a moderate to high amount of additives and preservatives in their daily life —this group will be referred to as Group 1—and people who eat very little to none—this group will be referred to as Group 2.

Author repeated the same experiment with another person, but the juice was poured by the author in SW and TS is of same volume. It is noticed that people have the tendency to choose SW more likely than TS.

We then recorded the initial color. We placed each tube in boiling water for one minute and recorded the color results and gave our conclusion. To test for starch using Lugol’s solution, we reused the test tubes and added a squirt of the solution. We recorded the final color and then our conclusion for each content. To test for lipids using paper towels, we placed a drop of solution and we let it stand for one minute. We then recorded our observation, if it was dry or not dry and wrote our conclusion for each sample. To test for proteins using Biuret’s reagent, we added a squirt of stock solution plus a few drops of Biuret’s solution. We wrote the initial color. We then shook the solution and waited for two minutes before recording the results. After the two minutes, we wrote the final color and conclusion for each content. For the unknowns, we wrote the odor and appearance of each content and then tested the benedict’s, starch, lipid, and protein test and wrote our conclusion.

The purpose of this paper is to provide a written report of the five part M&M project. Part one was sampling. We were to purchase 3 bags of M&M and record the color counts of each bag in an Excel spread sheet. For part two we calculated the sample proportions for each color, the mean number of candies per1.69oz bag, created a histogram for the number of candies per bag, use Excel to compute the descriptive statistics for the total number of candies per bag and summarize the information. In part three we located the 95% confidence interval for the proportion of blue, orange, green, yellow, red and brown. For part four we tested claims for percentages of each color. In the final part of the project we tested the hypothesis

	Another important idea proposed by Mintz is that sweetness is naturally desired by humans. He supports this by reporting on the work of researchers studying infants in the United States and how they are drawn to sweetness without having prior experience with it. He also states on page 15 that Alaskan Eskimos "consume sucrose despite the discomforts associated with the offending items."

In order to obtain a random sample, three bags of M&Ms were purchased from different locations. Each bag of M&Ms was a 1.69oz bag that was the standard plain version of the candy. The M&Ms were then sorted by color and this data was collected and compiled. These results were also added to a larger sample

When conducting the experiment the results for each alcohol were where they were anticipated to be supporting the

The process of tasting is happy for me, I enjoy the feeling that food melt in my mouse and the flavour disperse gradually. But it also exists some problems, I have the keen taste sense and smell over the average,
