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:
$3,000
Explanation:
Warranty expense is an obligation on the business because business is liable to accept the claims of warranty. A estimated percentage of warranty expense is charges as an expense in each period.
Total Sales = $500 x 6,000 units = $3,000,000
Warranty Expense for the year = Sales units x 3% x warranty cost per unit
Warranty Expense for the year = 6,000 x 3% x $50 = $9,000
Recognised warranty cost in the year = 120 units x $50 = $6,000
Accrued Warranty expense = $9,000 - $6,000 = $3,000
The answer is
D. Pre-incident activities include planning to prepare and establish a JIC in every incident requiring emergency response.
Good judgement is important in making decisions when budgeting because they can allow one to predict fairly accurately what the costs will be of a particular project based on one's own experience and of the current prices of supplies and say drilling charge rates and also with an adequate allowance for contingency.
