(f) If statistically significant, do you think the difference is large enough to be important? If so, to whom, and why? (g) Is the normality assumption fulfilled? Explain. (Pages 397-399) a) State the Hypothesis: (Pages 347-348) a. H0: There is no significant difference in the accident rate of red fire trucks compared to yellow fire trucks.
Therefore, there isn’t a high degree of correlation between the units produced and the amount of manufacturing overhead used. 2. How much overhead cost do you think Bridgeton and the consultants implicitly assumed would be saved by outsourcing muffler-exhaust systems and oil pans? They expect all overhead specific to product line of Muffler – Exhaust systems and oil pans would be saved, which is ($5,766,000+6,532,000)*434% = $533,733,20 (using 1988 data for estimate). 3.
Although the data are slightly right skewed, because of the large sample size(n=152) our inference on the mean is valid, by the Central Limit Therom. The Box Cox plot suggests a power transformation using a power, p= -0.5 would make the data more shaped like a normal distribution. The Normal Q-Q plot shows the transformed data points lying close to the straight line and the box plot of the transformed data looks symmetric with two outliers. The numerical summary of the transformed data confirms that the transformed data are symmetric (mean=1 and median=1). A Shapiro-Wilk test on the transformed data provides no evidence against the transformed data having come fro a normal distribution (P-value=0.4286).
158,012 tons per yr. of carbon dioxide What are the U.S. average household emissions? 31,308 lbs. per month What was your reduced emissions? 1,473 tons of c02 emissions Household Emissions Savings (Answers can be found above bar graphs If you took all actions you would reduce annual emissions by: 1,473 tons of c02 emissions If you took all actions your potential dollar savings would be: $78.00 per yr. Your new total annual estimated CO2 emissions: 156,539 lbs.
In 2010 approximately 85 million tons of municipal solid waste was recycled. This accumulated to saving more than 1.3 quadrillion Btu of energy which is equivalent to over 229 million barrels of oil (Environmental Protection Agency, 2013). A second is Reusable bags. As convenient as paper or plastic are when at the store both paper and plastic are harmful to the environment. In 1999 the American Forest and Paper Association found that in the United States alone 10 billion paper bags where used (Larry West, Paper Plastic or Something Better).
What will be the cost to refine 10,000 barrels of oil from Alaska’s Prudhoe Bay, which requires 80% of the refinery’s capability? (20% of grade) 2000/(150-1.5x)= 2000/150-1.5(80)= 2000/30 66.67 b. What will be the cost to refine 10,000 barrels of oil from West Texas Intermediate, which requires 75% of the refinery’s capability? (20% of grade) 2000/(150-1.5x)= 2000/150-1.5(75)= 2000/37.5= 53.33 c. For what value is the equation undefined? (20% of grade) The equation is undefined at 100%, because 150-(1.5*100)=0 and you cannot divide by 0 2.
They have a very informative website in which we were able to resource valuable information on the differences of sea and table salt (Mortonsalt.com). The major variance in the two types of salt is the way they are harvested. Table salt is taken from terrestrial salt deposits that are mined, heat-blasted and chemically treated. In this procedure, table salt is stripped of all minerals other than sodium chloride, leaving the final product 99.9 % Na Cl
Along these lines, seventy five percent of groundwater is viewed as nonrenewable. (O.E.FRANKE) • Hypothesis/Predicted Outcome : In view of the data gave, I trust that extra time the human advancement will have a negative impact on the ground water creating a critical decline in water levels. • Methods : With a specific end goal to accumulate the data for this lab, I made a diagram featuring the "Effect to Forest", "Groundwater Levels", "Saltwater Intrusion", "Cultivating", "Modern Development", and "Populace". I will then screen and record the time movement of introduction and human improvement on every beginning from the 1800s, 1900s and 2000s • Results/Outcome In a far reaching U.S. Geographical Survey study, amassing of nitrogen in almost a large portion of the streams examined in agrarian ranges positioned among the most elevated of all streams measured. In addition, the most astounding rates of recognition for the most vigorously utilized herbicides (atrazine, metolachlor, alachlor, and cyanazine) were found in streams and shallow groundwater in farming zones (Fuhrer et al, 1999).
Nuclear fission produces no greenhouse emissions (Alexander 1). This is also good for our atmosphere (Alexander 1). As nuclear energy is produced, there are no sulfur dioxide or nitrogen oxides being produced with it, unlike the burning of fossil fuels (Rastogi 1). These oxides can cause acid rain which is very bad for the environment
The reason why knowledge is not a basic good is because hedonism gives it no value toward the evaluation of lives. Here I will provide an example of how this works. Suppose there are two people. Person # 1 has 100 hedons, 0 dolars, and 10 percent knowledge. Person # 2 has 100 hedons, 0 dolars, and 90 percent knowledge.
