A variable X denoting differential percentage of sales of a product fluctuates year-by-year due to exogenous market factors as given below. Further, suppose X (in %)=[X0+(X)]% with Xo=50% and X as tabulated above denotes a RV with sample-sizes represented by n for each year as listed below: (i) Find, AM, HM and GM of the RV: X (ii) Decide the appropriate type and value of mean value of X that denotes rationally, the average statistical performance of the differential percentage change (X) of the sales (iii) Find the expected value and standard deviation of the RV,X=[X0+(X)]% with X0=50% (iv) Find mode of the RV,X=[Xo+(X)]% with X0=50% (v) Determine: p(X) from (UB of X ) to Median; and p(X) from Median to LB of X
