State your conclusion.
Reject Ho: We cannot conclude that the relationship between x and y is significant.
Do not reject Ho. We cannot conclude that the relationship between x and y is significant.
Do not reject Ho. We conclude that the relationship between x and y is significant.
Reject Ho: We conclude that the relationship between x and y is significant.
Write the null and alternative hypothesis for each claim. Remember to use the difference notation D.
