The following data relate the sales figures of the bar in Mark Kaltenbach's small bed-and-breakfast inn in Portland, to the number of guests registered that week: Week Guests Bar Sales 1 16 $340 2 12 $270 3 18 $380 4 14 $315

a) The simple linear regressionLOADING... equation that relates bar sales to number of guests (not to time) is (round your responses to one decimal place): Bar Sales = nothing + nothingtimesguests
b) If the forecast is 30 guests next week, the bar sales are expected to be $ nothing (round your response to one decimal place).

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
