Function used to measure decline in labour hours per unit as units of production increases is called

82.
In linear cost function, which is y = a + bx, y is classified as

83.
In specification analysis, assumptions related to linearity states but linearity must be within

84.
In regression analysis, if predicted cost value is 65 and observed cost value is 19 then disturbance term will be

85.
In adjustment issues of costing, database must consider wide range values of

86.
Method, which considers cost and cost drivers of departments such as employee relations and process engineering is termed as

87.
Examples of nonlinear cost functions are

88.
Relationship between cost and cost driver is economically plausible if goodness of fit

89.
Situation in which two or more independent variables are highly correlated is known as

90.
First step in estimation of cost function by using quantitative analysis is to
