Listed below are annual data for various years. The data are weights (metric tons) of imported lemons and car crash fatality rates per 100,000 population. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using alpha= 0.05. Is there sufficient evidence to conclude that there is a linear correlation between lemon imports and crash fatality rates? Do the results suggest that imported lemons cause car fatalities?

Listed below are the log body weights and log brain weights of
the primates species in the data set ”mammals”. Find the equation
of the least squares line with y = log brain weight and x = log
body weight. Do it by hand, by constructing a table like the one in
Example 9.1. Then do it with your calculator as efficiently as
possible. Finally, use the lm function in R to do it by creating a
linear model object...

The data in the table represent the weights of various domestic
cars and their miles per gallon in the city for the 2008 model
year. For the data from the first 11 cars, the least-squares
regression line is y=−0.0062x+42.4755. A twelfth car weighs 2,705
pounds and gets 14 miles per gallon. Compute the coefficient of
determination of the expanded data set (including the twelfth
car). What effect does the addition of the twelfth car to the data
set have on...
