Question: The data from exercise 1 follow.

Xi 1 2 3 4 5

Yi 3 7 5 11 14

  1. Use equation (12.23) to estimate the standard deviation of yp when x=4
  2. Use expression (12.24) to develop a 95% confidence interval for the expected value of y when x=4.
  3. Use equation (12.26) to estimate the standard deviation of an individual value of y when x=4
  4. Use expression (12.27) to develop a 95% prediction interval for y when x=4.
