A sports scientist expects resting pulse rate to decrease as weekly training time increases. For a random sample of 13 athletes, r=−0.604r=-0.604r=−0.604. The lower-tail critical values are -0.475 at 5% and -0.634 at 1%.
Carry out the test at the 5% significance level.
Explain why the evidence is not significant at the 1% level.
