The experimenter who collected the data in Exercise 11.68
Chapter 11, Problem 73E(choose chapter or problem)
The experimenter who collected the data in Exercise 11.68 claims that the minimum value of E(Y ) occurs at x = 1. Test this claim at the 5% significance level. [Hint: \(E(Y)=\beta_{0}+\beta_{1} x+\beta_{2} x_{2}\) has its minimum at the point \(x_{0}\), which satisfies the equation \(\beta_{1}+2 \beta_{2} x_{0}=0\)
Equation transcription:
Text transcription:
E(Y)=beta{0}+\beta{1} x+beta{2} x{2}
X{0}
beta{1}+2 beta{2} x{0}=0
