Explanation / Answer
a) .384 b) 2.30 because the .25 is included in both heights so it doesn'tvary and its needed to be rounded to 2 decimals c) The answer is 66.02 because you first plug 25.6 into y. Thensubtract the .25 over. Finally divide by the .384 to get the xanswer. x is the height. d) Actual - Expected equals residual. so 64-66.02 = -2.02 The residual is -2.02 I hope this helps.
