Question

Refer to the table of data given in Exercise 1 and use the heights and interval after times.
a. Construct a scatterplot. What does the scatterplot suggest about a linear correlation between heights of eruptions and interval-after times?
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 heights of eruptions and interval after times.
c. Letting y represent the interval-after time and letting x represent height, find the regression equation.
d. Based on the given sample data, what is the best predicted interval-after time for an eruption with a height of 100 ft?
