Week Three Discussion Questions • Can the probability be more than 1 or less than 0? Explain why or why not. According to the Statistics for Business and Economics book, probabilities have to follow two basic rules and one of them is that the number has to be between 0 and 1. Therefore, the probability cannot be more than 1 and less than 0. • Based on the data collected on a typical day, what is the probability that oil change will take 15 minutes or less time?
AP® ENVIRONMENTAL SCIENCE 2008 SCORING GUIDELINES Question 2 (a) Calculate the volume, in m3, of each of the following: (Two points can be earned in each of parts (a)(i) and (a)(ii): 1 point for a correct setup, and 1 point for the correct answer.) (i) The water infiltrated through the landfill per year 200 mm rain × 10,000 m2 1m = 0.2 m rain 1,000 mm 0.2 m 50% infiltrated water 100% water = 1,000 m3 (ii) The leachate that is treated per year 1,000 m3 × 0.9 (90%) = 900 m3 Note: If the answer to (a)(i) is incorrect, then 0.9 times that answer still earns full credit in (a)(ii). (b) Given that the cadmium concentration in the water draining from the landfill is 2.0 g/m3, calculate the mass, in kg, of cadmium that
Was there a normal distribution? Defend your position by interpreting the normality tests. (0 marks as this question is part of data screening for the writing of the results in Task 10) The results show that the test is not significant as according to Smirnov and Shapiro-Wilk, the sig. =.200, .175, .183 and .122, which are greater than .05. Thus meaning that the assumption of normality was met According to skewness and kurtosis there is no problem with normality as both scores of -1.57 (skewness) and -0.39 (kurtosis) are both within the range of +/- 3.29.
Rochelle decided to compare two plants for 50 days, Memphis plant-which will have the vector drive and Birmingham plant-which will use the existing system and prepare a report. The financial analysts believe that the purchase can be justified if the equipment leads to the average increase in production of atleast 10,000 bricks per day. Since we have to check whether the difference between the mean value of the bricks per day at Memphis plant and Birmingham plant is greater than 10000(for purchase to be justified), we will use hypothesis testing for means and compare the sampling distribution of the mean value of bricks produced in a day. This method is the typical method to solve these kind of problems. Data available is Plant Total Bricks produced in 50 days S (standard deviation) x̄ (mean) Memphis 7484500 3402.46 149690 Birmingham 6902350 3364.68 138047 Hypothesis test In a hypothesis test we assume Ho to be true and try to find evidence that shows otherwise.
Christopher Nelson Intermediate Accounting II Research Case 1 1. As of December 31, 2011, what amount, if any , of sales taxes due should be recognized in eVade’s financial statements? Assuming the financial statements for year ending 12/31/2011 have not been issued, an adjustment to sales tax liability can be recognized for the entire $25,000.000. As well, affected prior period statements will need to be re-stated. This is consistent with FASB codification ASC250-10-45-23 2.
To forecast 2010 sales based on 2009 sales, Equation 1 must be used: St = $500,000 + $1.10St–1 S2010 = $500,000 + $1.10($1,500,000) = $2,150,000 3. Equation 2 requires a forecast of gross domestic product. Equation 3 uses the actual gross domestic product for the past year and, therefore, is observable. 4. Advantages: Using the highest R2, the lowest
CASE FOUR:MEASUREMENT AND VALIDATION | 1. In Table 3.1, the traditional selection model shows a high p-value of 0.26 for education being citizenship and absence. The correlation score is 0.01, which means that education has little to no impact on the correlation between education and citizenship and absence. The interview score also has a p-value of 0.26, so this means that the interview score also does not relate to the correlation between performance and the interview. If the company is going to use the traditional selection model, it would do best by seeking out the lowest p-value with a high correlation score.
He is claimed as a dependant on other tax return, so we cannot deduct him as an exemption. So, $3000-$5700=-$2700, which is less than zero, so his taxable income is $0. 13-55. 2008 $200,000 $50,000 $25,000 25 $ 6,250 ($25,000*($50,000/$200,000)) 2009 $300,000 $81,000 $80,000 27 21,600 ($80,000*($81,000/$300,000)) 2010 $400,000 $96,000 $125,000 24 30,000 ($125,000*($96,000/$400,000)) Total taxable income
