Using the r calculated, test significance of correlation coefficient using a = 0.01 and claim k = 0. Draw the test using 7-steps hypothesis test.
1) H0 : k = 0
Ha : k
2) a = 0.01
3) Determine the test statistic t.
4) Determine the critical t0
5) Define the rejection region.
6) State the statistical decision.
7) Application interpretation.
