Please refer to the attached Microsoft Word document pertaining to homework instructions.

Consider the following results of measurements of a function P(t):

T 0 1 2 3 4

P 100 101 108 140 230

Assume that the data set can be modeled by a function P = P0 + B ta

a) Determine P0.

Use the Ln-test (logarithm) to show that the function P = P0 + B ta can be used to model the data set.

b) Use a linearized model to calculate the model parameters a and b

such that the least-squares error becomes minimal.

c) Calculate the relative model error (not the least-squares error).
