Using paired sample data consisting of the duration time (in seconds) of eruptions of Old Faithful geyser

Question:

Using paired sample data consisting of the duration time (in seconds) of eruptions of Old Faithful geyser and the time interval (in minutes) after the eruption, a value of r2 = 0.926 is calculated, indicating that about 93% of the variation in the interval after eruption can be explained by the relationship between those two variables as described by the best-fit line
