$500 (= $25 ´ 20 radios not stolen due to hiring 1 guard) c. 4 Chapter 4 Applied Problem 1. a. The intercept a is expected to be positive because even if no advertising is undertaken, some sales are expected to occur. b is expected to have a positive sign since Vanguard's sales are positively related to its level of advertising expenditures. Vanguard's sales should be inversely related to its rivals' expenditures on advertising, so c is expected to be negative. b. a is the sales of Bright Side detergent when neither Vanguard nor its rivals advertise.
The R-squared value shows us the correlation between the two variables in each graph that we were comparing. A consistent, precise R-squared value would be ideally 1. In all three cases, only one of our methods gave us this result: Titration. So given our results titration was the most precise method. But, our Ideal Gas Law method was more precise than crystallization from the previous week due to our newly found R-squared value of 0.8909.
Figure 4a shows data on REACTION RATE vs. the effects of enzyme inhibition experiment. The enzyme did not work with the inhibitor. 5) DISSCUSION Our hypothesis was that while trying to determine the optimum temperature for peroxidase the enzyme was going to denature or that the enzyme activity was going to increase at 60°C. Based on our results we concluded that it was a moderate inhibitor because as the temperature increased the reaction rate (absorbance) also increased instead of decreasing. For the effect of the pH on the peroxidase we did think that the pH5 was going to have the greatest amount of absorbance because it reacted well and it had the most enzyme.
The relationship between Hamstring strength index 60 degree/s and the Shuttle run test is a negative relationship due to r moves away from zero in negative direction and r = −0.149, the strength of this negative relationships would be weak with r -0.5 r=-0.528**, is more significant since p =0.002< 0.01, where r = −0.498** is significant at p =0.004< 0.01. The smaller the p-value in a test of hypothesis the more significant the results are. 8. The researchers stated that the study showed a positive, significant correlation between Quadriceps strength indices and pre- and postoperative functional stability Considering the data presented in the Table 5, do you agree with their statement? Provide a rationale for your answer.
While hydrogen bonds have a uniquely high surface tension, van der Waals forces have a relatively weak attraction, which causes low surface tension. According to an author of Chem Guide, Jim Clark, in van der Waals forces, “the electrons are mobile, and at any one instant they might find themselves towards one end of the molecule, making that end slightly positive” (2000). In other words, oil is NOT a polar molecule like water, which causes the molecules to not stick to each other as well. The reason tension would occur is because the
We thought that Product Innovation was the most important key success factor along with quality, and global strategy. We didn’t think that cost competitiveness was that important because Nike, Under Armour, and Adidas aren’t a best cost provider in fact they seem to be a differentiated provider. We believed that Under Armour was better than the other companies in product innovation because of all their advanced moisture-wicking fabric. Global strategy was also really important to us because that company has to focus on other countries besides the one that it is in. And with Under Armour struggling with their sales revenue in foreign countries we gave them a nine compared to Nike that we felt was a ten because a lot of their revenue comes from other countries.
We thought that a pH level of 3 would be the optimal pH level for the enzyme catecholase and its substrate catechol to react in. There was no prior knowledge on the effect of pH levels on catecholase and catechol. The results of the experiment did not confirm this hypothesis; instead the hypothesis was rejected by the results of the experiment. The results showed that tube 1 had the slowest rate of reaction, and actually did not react at all. The results showed that tube 2 had the fastest rate of reaction; this tube was exposed to the neutral pH of 7.
Urine tests are the least expensive for employers and are considered an intrusive method of testing. This test can be done at home, but do require lab verification for accurate results. A urine test can detect use primarily within the past week. However the test can be affected by abstaining from use for a period before the test, and are often temperature tested to insure sample integrity. Saliva tests are a little more expensive than urine testing and considered a relatively intrusive method of drug testing, therefore becoming more commonly used by employers.
Since one of the goals of this project is to obtain the highest value for the R2 or adjusted R2 statistics to estimate fair market value price for local housing; the adjusted R2 statistics value obtained from the five-variable model will not be used due to having lower value than the one obtained from a three variable model. This is an indication that adding information on X2 (number of car garage) and X4 ( number of bathrooms) do not appear to help to explain selling prices in any significant way when X1, X3 and X5 are already in the model. | The Best Model: | The best model is the model whose regression analysis resulted in the highest value for the R2 or adjusted R2 statistics. And this model is the regression model with three variables represented by: X1 – Total Floor Area X3 – Total Number of Bedrooms X5 – Either being sold directly by the owner or through a realtor agentThe regression functions for this model is: Ŷi = 134.929 + 0.108X1 – 25.696X3 + 51.79X5 [±2(51.482)]
Unilever has one detergent powder that is very good quality in the Omo, but it are priced higher than lower income individuals would pay. Unilever has cheaper brands, in the Minerva and Campeiro. They are both affordable for the lower income market, but do not have as strong cleaning power. The competitors of Unilever’s detergent powders are mainly Ace and P&G who pose little threat in the lower income market because there quality and price point is matched similar to the Minerva brand.
