In the standard regression equation y = a + bx, how is the letter b best described?
Answer(s): D
In the standard regression equation, b represents the variable coefficient. For example, in a cost determination regression, equals total costs, b is the variable cost per unit, is the number of units produced, and a is fixed cost. In preparing the annual profit plan for the coming year, Wilkens Company wants to determine the cost behavior pattern of the maintenance costs.Wilkens has decided to use linear regression by employing the equation = a + bx for maintenance costs. The prior year's data regarding maintenance hours and costs, and the results of the regression analysis, are given below and in the opposite column.
How is the letter x in the standard regression equation best described?
Answer(s): A
The letters x in the standard regression equation is the independent variable. For example, in a regression to determine the total cost of production, equal units produced. In preparing the annual profit plan for the coming year, Wilkens Company wants to determine the cost behavior pattern of the maintenance costs. Wilkens has decided to use linear regression by employing the equation = a + bx for maintenance costs. The prior year's data regarding maintenance hours and costs, and the results of the regression analysis, are given below and in the opposite column.
Based upon the data derived from the regression analysis, 420 maintenance hours in a month would mean the maintenance costs rounded to the nearest U dollar) would be budgeted at
Substituting the given data into the regression equation results in a budgeted cost o US $3,746 rounded to the nearest US dollar).y = a + bx y = 684.65 + 7.2884 420y = us $3,746
What is the percentage of the total variance that can be explained by the regression?
The coefficient of determination r) measures the percentage of the total variance in cost that can be explained by the regression equation. If the coefficient of determination is .99724, 99.724% of the variance is explained by the regression equation. Thus, the values in the regression equation explain virtually the entire amount of total cost.
An internal auditor for a large automotive parts retailer wishes to perform a risk analysis and wants to use an appropriate statistical tool to help identify stores that would be out of line compared to the majority of stores. The most appropriate statistical tool to use is
Answer(s): B
Time series data pertain to a given entity over a number of prior time periods. Cross sectional data, however, pertain to different entities for a given time period or at a given time.Thus, cross-sectional regression analysis is the most appropriate statistical tool because it compares attributes of all stores' operating statistics at one moment in time.

excelent material
the new versoin of this exam which i downloaded has all the latest questions from the exam. i only saw 3 new questions in the exam which was not in this dump.
question 8 - can cloudtrail be used for storing jobs? based on aws - aws cloudtrail is used for governance, compliance and investigating api usage across all of our aws accounts. every action that is taken by a user or script is an api call so this is logged to [aws] cloudtrail. something seems incorrect here.
question 13 tda - c01 answer : quick table calculation -> percentage of total , compute using table down
pls share teh dump
question 44 answer is user risk
please post the questions for preparation
thanks for the questions
please reopen it now ..its really urgent
these practice exam questions were exactly what i needed. the variety of questions and the realistic exam-like environment they created helped me assess my strengths and weaknesses. i felt more confident and well-prepared on exam day, and i owe it to this exam dumps!
thank u it very instructuf
its helpful?
is this dump still valid???
question 205 answer is b
question 39, should be answer b, directions stated is being sudneted from /21 to a /23. a /23 has 512 ips so 510 hosts. and can make 4 subnets out of the /21
beautiful test engine software and very helpful. questions are same as in the real exam. i passed my paper.
the questions are exactly the same in real exam. just make sure not to answer all them correct or else they suspect you are cheating.
question: 78 the right answer i think is d not a
very helpful
i am writing this exam tomorrow and have dumps
can i have the icdl excel exam
please upload it
hye when will post again the past year question for this h13-311_v3 part since i have to for my test tommorow…thank you very much
on question 22, option b-once per session is also valid.
this website is very helpful
its my first time exam
