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.

Equation Transcription:

$r=0.15$

${H}_{0}:\rho{}\leq{}0$

${H}_{1}:\rho{}>0$

$\rho{}>0$

Text Transcription:

r=0.15

H_0:rho{</=}0

H_1:rho>0

rho>0
