Question

1. The built-in data set faithful gives data on eruptions of the Old Faithful geyser in Yellowstone National Park. Each observation has a length of time the eruption lasted ( eruptions ) and the length of time until the next eruption ( waiting ), both in minutes. a. Find the equation of the regression line to explain waiting as a function of eruptions. b. Plot the data and the regression line. c. How long do you expect to wait after a 4.3 minute eruption?

Step 1

In R, we can use the lm() function to do this. Here is an example: ```R # Perform linear regression model <- lm(waiting ~ eruptions, data = faithful) # Print the coefficients of the model print(coef(model)) ``` This will give us the intercept and slope of the Show more…
