For a sample of 20 students, the correlation coefficient is $0.40 .$ Using the .01 significance level, can we conclude that there is a positive correlation between the variables? $?$
A study of 8 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.76. State the decision rule for 0.010 significance level: H0: Ļ ā¤ 0; H1: Ļ > 0. (Round your answer to 3 decimal places.)
