Table 2.5 (page 109) gives data on the true calories in 10 foods
and the average guesses made by a large group of people. Exercise
2.26 explored the influence of two outlying observations on the
correlation.
(a) Make a scatterplot suitable for predicting guessed calories
from true calories. Circle the points for spaghetti and snack cake
on your plot. These points lie outside the linear pattern of the
other 8 points.
(b) Find the least-squares regression line of guessed calories...

Use the following population data for the next question(s). At a
bird watching center, the number of yellow throated warblers
observed over Memorial Day Weekend was: three on Saturday, 10 on
Sunday, and eight on Monday. Assume sample sizes of two are
randomly selected with replacement from this population.
10) List the nine different possible samples of yellow throated
warblers and find the mean of each of them.
