Which set of characteristics will produce the smallest value for the estimated standard error?
That all observations are exactly the same.
If hetroseedasticity is present the conventional t and f test are invalid?
Heteroscedasticity refers to the situation in regression analysis where the variance of the errors is not constant across all levels of the independent variable(s). When heteroscedasticity is present, it can lead to biased standard errors, which in turn affects the validity of the conventional t and F tests. This means that the tests may produce misleading results regarding the significance of coefficients, potentially leading to incorrect conclusions. Therefore, it is crucial to detect and address heteroscedasticity to ensure reliable statistical inference.
What are the advantages and drawbacks of using gold standard?
Unfortunately there are disadvantages to the gold standard. One of the main disadvantages of implementation is that a gold standard would artificially inflate gold's value, increasing the cost of items and industrial process in which it is used. Another disadvantage is under the gold standard, gold mined at a different rate than the economy grows can produce both inflation, when deposits are discovered and extracted and deflation when they are mined to exhaustion
The following information pertains to the estimated number of labor hours required to produce certain units of the WARTHOG system. What is the learning curve percentage assumed by this data and how ma?
To determine the learning curve percentage from the estimated number of labor hours required to produce the WARTHOG system, you typically analyze the reduction in hours needed as production doubles. The learning curve percentage represents the consistent percentage reduction in labor hours each time the cumulative production doubles. If you provide the specific labor hour data, I could assist in calculating the exact learning curve percentage.
What are the largest copper producers in the U.S.?
Three companies produce over 95 percent of U.S. copper: Phelps Dodge, Inc., Asarco, Inc. (owned by Grupo Mexico S.A. de C.V.) and Kennecott Utah Copper Corp.
Which of the following samples will produce the largest value for the estimated standard error?
A small sample size and a large sample variance.
What is the difference between negative price variance and volume variance?
Negative price variance is when the cost is less than budgeted. Volume variance is a variance in the volume produce.
Which set of characteristics will produce the smallest value for the estimated standard error?
That all observations are exactly the same.
What is standar?
Under standard costing standard costs are determined which are required to produce one unit of product and then variance analysis is done to find out if there is any variations form standards costs and actual costs and then try to eliminate those variations. The whole process is called standard costing.
What variance is best for measuring operating performance?
Efficiency variance can be a good metric because it measures how efficiently inputs were used to produce output.
What is standared costing?
Under standard costing standard costs are determined which are required to produce one unit of product and then variance analysis is done to find out if there is any variations form standards costs and actual costs and then try to eliminate those variations. The whole process is called standard costing.
Favorable materials quanity variance?
In cost accounting, a variance is the difference between what we expected to happen (what we planned for when we created the budget) and what actually happened. If we produce more units from a given quantity of raw material than we expected to produce when we set up the budget, we have a favorable materials quantity variance, because we produced the goods more efficiently than we had planned for. We have used the raw materials with less waste than expected.
