(a) Use the regression feature of a graphing utility to find the equation of the least squares regression line that fits the data. Let t = 0 represent 2000. (Round the slope and y-intercept to two decimal places.) N = (b) Use the graphing utility to create a scatter plot of the data. Then graph the model you found in part (a) and the scatter plot in the same viewing window. How closely does the model represent the data? The model is a good fit to the actual data. The model is not a good fit to the actual data. (c) Use the model to estimate the number of television sets in U. S. households in 2007. (Round your answer to one decimal place.) N = 3 million (d) Use your school's library, the Internet, or some other reference source to analyze the accuracy of the estimate in part (c).
