Question
Data from n= 227 eruptions of the Old Faithful geyser in the United States are used to study the straight-line relationship between y = time to next eruption (minutes) and x = duration of the present eruption (minutes). Below is a plot of the data with the regression line superimposed 1.

a) 95% confidence interval, the confidence interval is an interval range of values that with 95% sure that the value would fall in between 81.715 to 83.844 when the duration of the eruption(Independent variable) at 4.5min.
b) Prediction interval: Prediction interval is an estimate of an interval in which that future observation would fall in between 70.367 to 95.191 interval range when the duration of present eruption at 4.5 min.
