The table on the right, from the Statistical Abstract of the United States, shows amusement park attendance at the top 15 amusement parks for given years.
a. Find the mean attendance, in thousands, for the 5 years shown, to the nearest integer.
b. Find the standard deviation, in thousands, for the years shown. Round to the nearest integer.

c. How many years had attendance within one standard deviation above or below the mean?
d. Represent the years using the numbers 9, 10, 11, 12, and 13 to keep computations easier. Look at the scatter plot. Do the data look linear?
e. Find the coefficient of correlation. Round to the nearest thousandth.
f. Find the linear regression equation. Round to the nearest thousandth.
g. Use your findings to predict the attendance at the top 15 amusement parks 2 years from the current year.
