You may need to use the appropriate appendix table or technology to answer this question. Given are five observations for two variables, X and y. (Round your answers to two decimal places.) (a) Use 537* = s l + ;_ to estimate the standard deviation of 9* when X = 5. n 2(X (b) Use V\" i tat/25 to develop a 95% confidence interval For the expected value of y when X = 5. f): |4.38 |x to | 12.32 |x * _ _ 2 (c) Use Spred = s 1 + i + g to estimate the standard deviation of an individual value of y when X = 5. n 2(Xi X)2 2.17 I (d) Use 9* i ta/Zspred to develop a 95% prediction interval for y when X = 5. |1.71 |x to|15.49 |x
