The geometric mean GM of a set of n positive numbers x1, x2, ... , xn is definedby:GM = ( xi. Xz . ... . xn ) llnWrite a user-defined function that calculates the geometric mean of a set ofnumbers. For function name and arguments use GM=Geomean (x) , wherethe input argument xis a vector of numbers (any length) and the output argumentGM is their geometric mean. The geometric mean is useful for calculatingthe average of rates. The following table gives the inflation rates in theUnited States from 1978 to 1987 (inflation of 7.6% means 1.076). Use theuser-defmed function Geomean to calculate the average inflation for the tenyearperiod.
