Eastern galvanising and gross domestic product per capita at Slovakia
PART A
Task A:
Eastern Electric produces television sets. The company wants to get a grasp on the sensitivity of the beat demanded of its product to the various factors that affect it.
a) beat a graph and suggest a simple reverse model for the data below.
b) Compute the coefficient of aspiration and explain the result.
c) designate a different approximation, compute the regression equation, coefficient of determination and par it with results in a) and b).
d) Explain the nature of this relationship.
Quantity demanded| come one-year income|
250| 28123|
330| 32350|
360| 33495|
380| 33540|
400| 33999|

460| 42900|
470| 43254|
480| 44001|
500| 44931|

Given data
heroism A:
a) and b) Make a graph and suggest a simple regression model for the data below. Compute the coefficient of determination and explain the result.
This linear equation shows the increase of average yearbook income as the quantity demanded grows. Coefficient of determination shows that the variation of quantity explained by the variation in the variables is non in perfect correlativity (R2 = 0,9116)and so this interpretation of data (linear model) does not perfectly find out this analysis. Linear regression model represents data relatively accurately and is easiest for managers to read from. This data shows us that Eastern Electric should throw the growing trend in productivity of their products because there is also a growth in quantity demanded by its customers. It is not possible to decide if the annual income of the company depends on the quantity demanded because there is no timeline which concerns these data (we should only estimate that the Average Annual Income are counted per...If you want to get a well(p) essay, order it on our website: Orderessay
