Refer to the table of data given in Exercise 1 and use the durations and heights.
a. Construct a scatterplot. What does the scatterplot suggest about a linear correlation between duration and height?
b. Find the value of the linear correlation coefficient and determine whether there is sufficient evidence to support a claim of a linear correlation between duration and height.
c. Letting y represent height and letting x represent duration, find the regression equation.
d. If an eruption has a duration of 200 sec, what is its best predicted height?
