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.) 2. 4. Y, 4 11 15 (a) Use S to estimate the standard deviation of when x-5, -S1 I(x, - x)² (b) Use * t to develop a 95% confidence interval for the expected value of y when x = 5. to ( - x) Zx, - x)2 (c) Use s pred S 1+ to estimate the standard deviation of an individual value of y when x - 5. (d) Use ttared to develop a 95% prediction interval for y when x - 5. to 1/- 3.
