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.) @) (b) (C) (d) x, 1 3 4 7,4 4 12 13 1 (x* - T02 . - - Use 59* = s _ + _2 to estimate the standard deVIation of y* when X = 5. n 2(xl. - X) Use 7* :E @st to develop a 95% confidence interval for the expected value of y when X = 5. Use spred = S to 1+i+ (x* 702 n 2(xi 702 to estimate the standard deviation of an individual value of y when x = 5. Use )'I* :i: ta/Zspred to develop a 95% prediction interval for y when x = 5. to
