Question:How The Index Numbers Are Constructed?

How The Index Numbers Are Constructed?

Its construction is a quite difficult process. Purpose of index number: The most important element which affects all the other factors while constructing the index number is the fixation f object of index number. If we do not have the pur...

Solve the system of equations:– x + 3y = 4–2x + 6y = 8a.0 { (x,y) │ x + y = 9 }b.0 { (x,y) │ x – y = 2 }c.0 { (x,y) │ 2x + 6y = –8 }d.0 { (x,y) │ x – 3y = –4 }Objective: Use time series data to forecast.No questions available for this objective at this time.Objective: Convert data to indices.5. What can be concluded about an index of 75?a.0 an error was made because an index cannot be less than 100b.0 there was no change because the starting index is 75c.0 there has been a decline of 25 percentage points from the base periodd.0 there was in increase of 25 percentWeek Three: Visual Representations of QuantitiesObjective: Construct histograms an bivariate plots.6.The monthly incomes for a group of 100 engineers is ranges between $2,200 and $3,700. What class width would you use if you wanted 5 classes?a.0 20b.0 150c.0 300d.0 200Objective: Determine the value of a slope by using the slope–intercept formula.7. What is the slope of the line: y = 2x + 3a.0 2b.0 3c.0 1/2d.0 1Objective: Conduct a linear regression analysis.8. Which statement best describes the slope of the regression line?a.0 It is always greater than 1.b.0 It is a positive number.c.0 It is the change in y for a unit change in x.d.0 A slope of –4 moves 4 units up for every 1 unit to the right.Week Four: Time Value of MoneyObjective: Calculate the time value of money.9.

What is the relationship between the variance and the standard deviation?a.0 Variance is the square root of the standard deviationb.0 Variance is the square of the standard deviationc.0 Variance is twice the standard deviationd.0 No constant relationship between the variance and the standard deviation existsObjective: Construct a normal distribution.12. What is the distribution with a mean of 0 and a standard deviation of 1 called?a.0 Frequency distributionb.0 Standard frequency distributionc.0 z–scored.0 Binomial probability distribution

A: 16 I think. or maybe 87.6, something like that.all the answers will be numbers. Except some might be letters I guess, I didnt read the questions
