Quick Minitab Question Please

[Niall101]

I have a scatterplot X is just 30 given values. Y is 2*X + eps, where eps is a random figure. The Plot is Y vs X

I am asked to fit 2 lines

Y= ax +b by least squared method

and

X = cy +d

Similarly

I do not know which command to use on minitab. Is this just standard regression? if so how do I fit the X = cy +d line. is there any difference?

Do I just use the fitted line plot? and if so how do i plot X = cy +d on the same graph??

Thanks in advance! ( and sorry if this is very basic I am new to minitab)

The regression command in Minitab can be found with this sequence of menu steps:

Stat --> Regression --> Regression

You will be asked to specify the response and predictor variables. Run the regression procedure twice - once with Y as response and x as predictor, the second time with the roles reversed.

If all you want is the fitted line plot (two of them, one for each of your cases)

Stat --> Regression --> Fitted Line Plot

and follow the same idea for specifying variables.
