Answer:
Explanation:
Data given and notation
represent the sample mean
represent the standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to determine if the mean is lower than 5600, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
Answer:
The statement is: False.
Explanation:
In supply chain management, incremental analysis is in charge of determining the cost of ordering one more additional unit of a product over the cost of no requesting that additional unit. The cost of overstimulating demand is the loss of ordering one additional unit and discovering that it cannot be sold. The cost of underestimating demand is the opportunity loss for nor requesting one additional and discovering it could have been sold.
<em>The cost of underestimating demand is more difficult to determine than the cost of overestimating demand because underestimating demand because it involves customer's desires</em> on purchasing a product when not having the resources to do so.
Answer:
Per Chevron 3Q 2013 Filling:
The percentage change in the cost of purchased oil products nine months to September 30, 2013 when compared to nine months in 2012 was:
2.47%
Explanation:
a) Data and Calculations:
Cost of purchased oil products:
2013 $34,822,000,000
2012 $33,982,000,000
Change $840,000,000
Percentage Change = $840/$33,982 x 100
= 2.47%
b) The implication is that Chevron's cost of purchased oil products in third quarter of 2013 increased by 2.47% when compared with the same period in 2012. This percentage change is calculated by subtracting the Q3 2012 cost of purchased oil products from the Q3 2013 cost of purchased oil products and then dividing the difference by the Q3 2012, and multiplying by 100. The change could be caused by increases in the price of oil products or other variables.
Answer:
The answer is: full disclosure principle
Explanation:
Full disclosure principle in accounting refers to the requirement that businesses are supposed to provide all material information pertaining to their operations to the stakeholders of the business so as to facilitate better decision-making frameworks when evaluating the business.
The going concern principle is based on the assumption that the business will not cease operating in the foreseeable future. The matching principle requires that the expenses incurred in carrying out an economic activity are recorded in the same period as the revenues earned from that activity. The historical cost principle requires assets or liabilities to be recorded at their acquisition value.
