Given are five observations for two variables, x and y. (Round your answers to two decimal places.) (a) Use sy^=sn1+(xix)2(xx)2 to estimate the standard deviation of y^ when x=4 (b) Use y^t/2sy^ to develop a 95% confidence interval for the expected value of y when x=4. to (c) Use spred=s1+n1+(xix)2(xx)2 to estimate the standard deviation of an individual value of y when x=4. (d) Use y^t/2S pred to develop a 95% prediction interval for y when x=4. to
