Question

Any source would be helpful for the code portion.

Problem 2 The time to complete an assembly task is to be modeled as a linear function of the complexity of the task and the time an assembler has been continuously working Complexity (x) is measured on a scale from 0 to 100, work time (y) is in hours prior to beginning the timed assembly, and completion time (Z) is in minutes. Use your result from Problem 1 and the following data to determine an equation of the regression plane that predicts the expected completion time. [Hint: use MATLAB to solve the system of three equations for the regression coefficients 90 75 60 60 90 75 5.6 3.8 2.0 2.4 5.2 2.9 4 0 4 0

Explanation / Answer

Here completion time (Z) is dependent variable and complexity (x) and work time (y) are independent variables.

This is the problem of multiple regression.

The regression equation will be,

Z = -4.25 + 0.1*x + 0.1*y

intercept = -4.25

slope = 0.1 and 0.1
