Question

Chapter 10.2, Problem 7UYK

(a)

To determine

To find: A scatterplot that shows the increase in research and development spending over time and whether the pattern suggest that the spending is increasing linearly over time.

(b)

To determine

To find: The equation of the least-square regression line for predicting spending from year and add this line to scatterplot.

(c)

To determine

To find: The residual for each of the years 2003, 2006 and 2009 and use these residuals to calculate standard error s.

(d)

To determine

To find: The regression model for the provided data and to estimate the unknown parameters in the model.

(e)

To determine

To find: A 95% confidence interval for the slope and summarize the information provided by the interval about the increase in spending over time.
