The value y (in 1982–1984 dollars) of each dollar paid by consumers in each of the years from 1994 through 2008 in a country is represented by the ordered pairs. ...... .. .. ..... .....

Let t = 4 represent 1994. Do the data appear linear? O Yes O No (b) Use the regression feature of the spreadsheet software program to find a linear model for the data. (Let t represent time. Round your numerical values to for places.) y = (c) Use the model to predict the value (in 1982-1984 dollars) of 1 dollar paid by consumers in 2010 and in 2011. (Round your answers to two decimal places.) 2010 2011 %24 Discuss the reliability of your predictions based on your scatter plot and the graph of your linear model for the data. O Because the data follow a linear pattern, the predictions for 2010 and 2011 are not reliable. O Because the data follow a linear pattern, the predictions for 2010 and 2011 are reliable. O Because the data does not follow a linear pattern, the predictions for 2010 and 2011 are not reliable. O Because the data does not follow a linear pattern, the predictions for 2010 and 2011 are reliable.
