Please Help is Part A in Matlab code.

Problem statement a (30 points) A gas well produces natural gas under natural depletion. Given the following production data, find the best poh nomial function (order of 2) to fit the data. Calculate the correlation coefficient Plot the polynomial model declins curve tosether with the original data on a same graph. When plotting the model decline curve, use time interval from 0 to i5 vears (180 months) t (month 10 20 30 40 S0 60 70 80 90 100 msct/d 9966 8270 7097 5932 5189 4733 4030 3571 3468 2992 2696 b (30 points) Use the same production data provided in (a), fit the data into a hy perbolic decline model 1+bD,)
