An Experiment Was Performed on a Certain Metal to Determine

question 11

Essay

An experiment was performed on a certain metal to determine if the strength is a function of heating time.The simple linear regression equation is
= 1 + 1X,and the sample coefficient of determination (r²)= .7777.The time is in minutes and the strength is measured in pounds per square inch.Test to determine if there is a significant correlation between the heating time and strength of the metal.Using H₀: ρ = 0 vs.H_A: ρ ≠ 0 at α = .05,determine the test statistic and decision.
