If you choose 40 random employees from the corporation, the standard error would equal 6/Square root of 40 = .95 days. The 12 days in this department corresponds to (12-8.2)/.95 = 4 standard errors above the corporation average of 8.2. This is much higher than two or three standard errors, and it appears to be beyond chance variation. Chapter 9 Exercise 3 The p- value tells you how likely it would be to get results at least as extreme as this if there was no difference in the taste and only chance variation was operating. In this problem, p-value of 0.02 means that, if there is no difference in taste, then there is only 2% chance that 70% or more people would declare one drink better than the
There is only a 1.28% chance that b = 0, which is better than the 10 percent level required by the marketing director. d. The exact level of significance of is 0.0927. There is a 9.27% chance that rivals’ spending on advertising does not affect Vanguard’s sales (i.e., b = 0), which is just barely better than the 10 percent level required by the marketing director. e. About 78 percent of the variation in sales remains unexplained. Find additional explanatory variables that have a significant affect on S. The manager might try adding the price of its detergent and the
a. Sales exceeded the budget by 10.7% ($75,000 ÷ $700,000), while cost of merchandise increased by 22.9% and salaries increased by only 11.4%. Thus, the investigation should focus on cost of merchandise since a 22.9% increase is disproportionate to the increase in sales. b. Electricity would not be a controllable cost for the manager of sporting goods, and it is doubtful that including it on a performance report for sporting goods would be
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. Our crystallization method only gave us a R-squared value of only 0.7735 which was the farthest value from
In addition, we can estimated that a customer with a $4000 credit balance to have an income in between (41.7665, 46.6130) in $1000 using the 95% CI confidence levels to calculate the income level. At the same time, the average mean income is (41.7665+46.6130)/2= 44.19 or $44,190 rounded up to nearest dollar. We cannot really predict the credit balance of $10,000 as it is out of
There is a very low probability (5% at most) that the annual income for the data from AJ DAVIS is less than $50,000. The way that we concluded this was to test the probability that the annual income of our customers is $50,000 versus the probability that the average annual income was less than $50,000. What we found was that there is a 95% chance that the average annual income of our customers is between $69,997.9 and $70,001.8. This was also backed with a p-value (which determines the strength of the evidence) that showed weak evidence against the average income equaling $50,000. Since we cannot deny that the annual income average is $50,000, we have no choice but to keep it as a consideration moving forward.
(Points : 5) sales under $1,000,000 no accountants on staff insignificant receivables and payables all sales and purchases on account 5. (TCO D) Two companies report the same cost of goods available for sale, but each employs a different inventory costing method. If the price of goods has increased during the period, then the company using _____. (Points : 5) LIFO will have the highest ending inventory FIFO will have the highest cost of goods sold FIFO will have the highest ending inventory LIFO will have the lowest cost of goods sold 6. (TCOs A, E) Equipment with a cost of $192,000 has an estimated salvage value of $18,000 and an estimated life of 4 years or 12,000 hours.
,Sarah L. G January 6, 2013 Written Assignment #1 1. A) $1,000 with 5% interest after 10 years gives you $1,628. Therefore, you would gain $628 in interest. B) If the interest is withdrawn each year, a total of $500 would be earned because the $1,000 investment would earn $50 of simple interest each year. C) The answers are different because if the interest is left untouched, it makes the principal amount higher each year, giving more money after 10 years.
Option two is the choice because the $2,716 savings difference in total interest from option two outweighs the $1,043 in interest savings from option one. Here the simulator reveals that loan option one is the correct choice. Loan option one is the best choice to solve the working capital shortfall because even though it has a higher interest rate, there is no prepayment limitation and has a total interest payment of only $32,603 after three months. The Financial Dictionary explains that “prepayment is good for the borrower because it relieves him/her of the debt, but it deprives the lender of interest he/she would have received otherwise” (Financial Dictionary, p. 1,
Livoria Sandwich Inc. is operating in a highly competitive and fast growing market. In 2011, the company had only 0.29% profit margin.
