In a sample of 300 steel rods, the correlation coefficient
Chapter 7, Problem 10E(choose chapter or problem)
In a sample of 300 steel rods, the correlation coefficient between diameter and length was \(r=0.15\).
a. Find the P-value for testing \(H_{0}: \rho \leq 0\) vs. \(H_{1}: \rho>0\). Can you conclude that \(\rho>0\)?
b. Does the result in part (a) allow you to conclude that there is a strong correlation between eccentricity and smoothness? Explain.
