Question

Problem # 8 The data show the bug chirps per minute at different temperatures. Find the regression equation, letting the first variable be the independent (X) variable. Find the best predicted temperature for a time when a bug is chirping at the rate of 3000 chirps per minute. Use a significance level of 0.05. What is wrong with this predicted value? Regression Equation------------------------------------------------------------------ The best predicted temperature when a bug is chirping at 3000 chirps per minute is -------- ----- Chirps (min) 1232 920 889 1035 1157 1098 Temperature 88.5 73.9 71.4 78.5 91.5 85.6

Answer 1

predicted value =20.4659+0.0579*3000 =194.2

this is wrong as x=3000 falls outside the range of x values on which this regression is based upon.
