Given are five observations for two variables, :1: and y. Use Table 2 of Appendix B. Round your answers to two decimal places. a. Using the following equation: Estimate the standard deviation of f; * when :1: = 4. b. Using the following expression: jog/283;: Develop a 95% condence interval for the expected value of y when m = 4. to c. Using the following equation: Estimate the standard deviation of an individual value of y when as = 4. d. Using the following expression: 21:] * ita/Zspred Develop a 95% prediction interval for y when :5 = 4. t0 Consider the data set below. Use Table 2 of Appendix B.
