a. Mean = 8.5
Mean = 9.9
Median 11
Median = 11
Mode 11
Mode = 7
Range = 15
Range = 15
Mean = 9.9
Mean = 9.9
Median = 13
Median = 13
Mode = 7
Mode = 11
Range = 19
Range = 19

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
