Given a set of data as x and y, find the RMS value between the data and its best fit curve from a first degree polynomial
Example
x = [1:10] y = [2 7 3 5 9 11 1 6 2 0]
bestfit_RMS = 3.3379

Nice problem Swapnali! Since it has a floating-point answer, you should specify how many significant digits you're looking for, or include a tolerance term in your test suite.
Thanks Ned. Can you please show me how can I add a torelance term for the answer in test suite?
something like this:
assert(abs(BestFit(x,y)-y_correct)<1e-5)
please allow for tolerance in precision of test case answers
