Each piece weighed on a very accurate scale. The results in grams were: 3.087 3.131 3.241 3.241 3.270 3.353 3.400 3.411 3.437 3.477 a. Construct a 90 % confidence interval for the true mean weight. b. What sample size would be necessary to estimate the true weight with an error of + or – 0.03 grams with a 90% confidence. c. Discuss the factors which might cause variation in the weight of Tootsie Rolls during manufacture.
The use of saccharin increased during World War I due to sugar shortages, and during the 1960s because of its production in usage of low-calorie foods (Zamora, 2011). Saccharin is used to sweeten drinks, candies, medicines, and toothpaste. In 1972, the USDA tried unsuccessfully to ban the use of this sweetener after research showed that it increased the rate of cancer in rats, but the warning labels were the only result in 2000. The NIH had removed saccharin from its list of carcinogens and later on the warning labels were also removed. The ingredients of Sweet'N Low are dextrose, 3.6% soluble saccharin, and small amounts of anti-caking agents.
3. The rate variance is calculated by the difference between the $16.90 actual labor rate vs the $16 budgeted rate, then we multiply the difference by the 9000 actual labor hours which gives us an $8,100 unfavorable rate variance. To figure out the efficiency variance we multiply the $16 budgeted rate by the difference between the 9,000 actual labor hours and the 10,000 budgeted hours, giving us a $16,000 favorable efficiency variance. As a result of the difference between the rate and efficiency variances we end up having a $7,900 favorable flexible budget variance. 4.
The masses were 99.997 g, 100.008 g, 100.011 g, and 100.005 g. What is the average mass of the watch glass? How many significant figures are in the measurement 102.400 meters? Convert the following measurement to scientific notation: 101 000 grams Complete the following problem: A piece of stone has a mass of 24.595 grams and a volume of 5.34 cm3. What is the density of the stone? (remember that
This consists of 8.03 g of sugar(dextrose) and 0.96 grams of starch (malt dextrin) 10 grams of Splenda has 33 Calories compared to 39 Calories for an equal amount of sugar. The calories in Splenda come from the carbohydrates in it. 3. Discuss safety and the sweetener that you have selected. A study of a component in Splenda (sucralose) concluded, “There is no indication that adverse effects on human health would occur from frequent or long-term exposure to sucralose at the maximum anticipated levels of intake”.
Vitamins are organic compounds needed in the diet in small amounts to promote and regulate the chemical reactions and processes needed for growth. For vitamin A, my DRI was 700 Amg. My intake was 265 Amg, which is an intake of 37%. Vitamin A deficiency can lead to eye disorders known as xerophthalmia, such as night blindness. The goal is to meet my DRI 100% so if I ate more animal products such as eggs and dietary products (cheese) I would increase my intake of vitamin A.
MnM Candy Report Strayer University Abstract In this report, we examine the proportions of M n M candies through random sampling of 60 bags. The bags used in the experiments were collected from different stores in wide region of the United States. In this research, we are comparing the percentages as well as quantities per bag are in range of the expected percentages set by Masterfood Manufacturing for Mars Company to the random samples that were collected by the class. After all tests have been conducted, the conclusion is that the quantity per bag varies from 53-58 pieces of candy as well as the percentages for each color vary. This variance can be due to the machine that separates and collects the candy that will be deposited into each bag and by the inspections of each bag for defects.
Hector N. Torres Jr. The effects of energy drinks on young adults Energy drink beverages claim to work by altering blood sugar levels with the purpose of increasing endurance, energy and performance. Its impact on performance has been tested for example Red Bull verified that it could reduce a drivers sleepiness and enhance driving performance during prolonged highway driving (Mets, et al., 2010). It has become a staple for college students with sales reaching $9 Billion in 2011. Despite the claims, scientific evidence contests these assertions.
The confidence interval for the first group mean is thus (4.1, 13.9). Similarly for the second group, the confidence interval for the mean is (12.1, 21.9). Notice that the two intervals overlap. However, the t-statistic for comparing two means is: t= 17 − 9 2.5 2 + 2.5 2 = 2.26 which reflects that the null hypothesis, that the means of the two groups are the same, should be rejected at the α = 0.05 level. To verify the above conclusion, consider the 95 percent confidence interval for the difference between the two group means: (17 − 9 ) ± 1.96 × 2.5 2 + 2.5 2 which yields (1.09, 14.91).
Body mass index is an approximate measure of whether someone is over- or underweight, calculated by dividing their weight in kilograms by the square of their height in meters. “Non-communicable diseases (NCDs) include a large group of non-infectious medical conditions; however cardiovascular disease, cancer, diabetes, and chronic respiratory diseases are highlighted more under this heading. In spite of being included in the recent, agenda of global development”, “the World Health Assembly also authorized a new health goal to reduce avoidable mortality from NCDs 25% by 2025, which is of great importance.” “26.6 million deaths worldwide were recorded in 1990s, from NCDs, which drastically increased to 34.5 million in 2010. Additionally, in 2008 the
