Sales growth. A marketing researcher studied annual sales of a product that had been introduced 10 years ago. The data are as follows, where X is the year (coded) and Y is sales in thousands of units: i: 1 2 3 4 5 6 7 8 9 10 Xi: 0 1 2 3 4 5 6 7 8 9 Yi: 98 135 162 178 221 232 283 300 374 395 a. Prepare a scatter plot of the data. Does a linear relation appear adequate here? b. Use the Box-Cox procedure and standardization (3.36) to find an appropriate power transformation of Y. Evaluate SSE for λ = .3, .4, .5, .6, .7. What transformation of Y is suggested? c. Use the transformation Y' = ∙∙Y and obtain the estimated linear regression function for the transformed data. d. Plot the estimated regression line and the transformed data. Does the regression line appear to be a good fit to the transformed data? e. Obtain the residuals and plot them against the fitted values. Also prepare a normal probability plot. What do your plots show? f. Express the estimated regression function in the original units.

Sales, in bottles per day, of my exclusive massproduced 2002 vintage Chateau Petit Mont Blanc follow the function $$s(t)=4.5 e^{-0.2 t} \sin (2 \pi t)$$ where $t$ is time in years since January 1,2002 . How fast were sales rising or falling on January $1,2003 ?$
