b. a is the sales of Bright Side detergent when neither Vanguard nor its rivals advertise. b is ΔS/ΔA, the increase in Bright Side sales attributable to a $1,000 per week increase in advertising expenditures by Vanguard. c is ΔS/ΔR, the decrease in Bright Side sales attributable to a $1,000 per week increase in advertising expenditures by Vanguard's rivals. c. The exact level of significance of is 0.0128. There is only a 1.28% chance that b = 0, which is better than the 10 percent level required by the marketing director.
Focus Question Should chemists prepare Zinc Iodide, from its elements or from a Double Replacement Reaction between Barium Iodide and Zinc Sulfate? -To put things into perspective in terms of cost efficiency, zinc granules cost about $62.50 per kilogram or $.0625 per gram. Also, Iodine chips cost about $.1498, Barium Iodide Dihydrate costs about $.886 per gram, and Zinc Sulfate Heptahydrate costs about $.0405 per gram. According the chemical reaction listed below, the double replacement reaction creates a solid Barium Sulfate precipitate This means that the ZnI2 is less pure than it would be from just the Zinc and the Iodine. With the elemental reaction you get ZnI2 as your only product thus indicated that it is “pure” Zinc Iodide.
20. mol H2 reacts with 8.0 mol O2 to produce H2O. Determine the number of grams reactant in excess and number of grams H2O produced. Identify the limiting reactant. 8.1 g H2 , 2.9 x 102 g H2O 17. How many litres of O2 gas are required to produce 100. g Al2O3?
Week 2 Cases C4-4 and C5-1 Carlos Carmona January 22, 2012 Benedictine University C4-4 Please See Attached Excel Document C5-1 1. Which company was the more profitable in 2006? (Hint: Compare ROE and ROA performance for the two grocery retailers.) Concentrating first thing on a comparing ROE, the Kroger Company performed better than Safeway in 2006. This is because Kroger’s ROE was 23.9% in comparison to 16.4% for Safeway.
If the reaction is first order, its graphical representation is seen as ln[A] (natural log of concentration) vs. time, and the slope of its like is also the negative rate constant. Finally, for a second order reaction the graph is shown as 1/[A] (inverse of concentration) vs. time, and the slope of its given line is the positive rate constant. By understanding the rate law and finding the value of the correct rate constant with respect to the order of the reaction, one can determine the half-life of the crystal violet. This is because the crystal violet undergoes a decay reaction with the sodium hydroxide. According to Beer's Law, the absorbance of crystal violet is proportional to its concentration.
Practice Test 4 –Bus 2023 Directions: For each question find the answer that is the best solution provided. There is only one correct answer. 1. For a sample size of 30, changing from using the standard normal distribution to using the t distribution in a hypothesis test, a. will result in the rejection region being smaller b. will result in the rejection region being larger c. would have no effect on the rejection region d. Not enough information is given to answer this question. ANSWER: a -recall that all the t-values are larger than the z-values so it makes it more difficult to reject the null.
I am somewhat confident with my answer because I used simulation process correctly to find the loss of revenue and also, I used random numbers for calculating this. There are some limitations with the simulation process. The first one is that the cumulative weeks will generally not add up to accurate 52 as in my work, the final cumulative week comes as 50.968 so this is not the revenue lost in exactly 1 year. Also, if we apply simulation again then we will get the different answer for revenue loss. Therefore, it is better to apply simulation a number of times and then take the average of all those
However, the promotion tactic of rebates has helped somewhat in the overall product promotion. While our advertizing and promotion expenditures have been markedly greater than of our competition, representing nearly 6.5% of sales, their effectiveness has not. To date, GCI has 74 local media inserts compared to only 56 of our closest competition and 47 of the top competitor. Clearly, one major task as we move into the sixth quarter and beyond is the revamping of our ads to make them more effective. As the data show, more is not better; especially if the ad is not effective in the first
In addition, we constantly checked the temperature inside the bucket to make sure we maintained a constant temperature. Results Measured Response Experiment In this experiment the 95% confidence interval is slightly larger in the darker intensities than in the normal light intensities (control sample). Therefore, the amount of variation is similar. The average rate of movement is clearly greater in darker intensities that in light intensities. The confidence intervals do overlap in this experiment; therefore the smaller light intensities does not have a signficant effect on the movment of Acheta domesticus as measured in 30 seconds.
In 2003 Samsung ranked 25 from number 34, which shows that it was able to compete and be successful in the market with its new products. Samsung’s debt of $15billion in 1997 has been reduced to $4.6 billion by 2002. It was also able to survive in the Asian financial crisis due to its product being different than its competitors. The net profit of $5.9 billion compared to $2.8 billion in
