Question:
American Statistician [1991]: 4 9).
a. What proportion of observed variation in time can be explained by the simple linear regression model?
b. Does the simple linear regression model appear to be useful?
c. Minitab reported that sa1b12002 5 .347. Calculate a
95% confidence interval for the mean time when depth 5 200 feet.
d. A single observation on time is to be made when drilling starts at a depth of 200 feet. Use a 95% prediction interval to predict the resulting value of time.
e. Minitab gave (8.147, 10.065) as a 95% confidence interval for mean time when depth = 300. Calculate a 99% confidence interval for this mean.
