Question

This exercise would help me to fimiliarize  with the realtionship among levels of significance,p-values, and rejection decisions. I need to indicatewhether I would reject or fail to reject the nullhypothesis. I am lost.

Explanation / Answer

We will reject the null hypothesis if p-value is smaller thanthe level of significance. a) Reject the null hypothesis, since p-value(=0.0007) is lessthan the level of significance(=0.001) b) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0650>0.05) c) Reject the null hypothesis, since p-value(=0.0097) is lessthan the level of significance(=0.01) d) Reject the null hypothesis, since p-value(=0.0399) is lessthan the level of significance(=0.05) e) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0110>0.001) f) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0101>0.01) Reject the null hypothesis, since p-value(=0.0097) is lessthan the level of significance(=0.01) d) Reject the null hypothesis, since p-value(=0.0399) is lessthan the level of significance(=0.05) e) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0110>0.001) f) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0101>0.01) Reject the null hypothesis, since p-value(=0.0399) is lessthan the level of significance(=0.05) e) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0110>0.001) f) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0101>0.01) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0110>0.001) f) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0101>0.01) Fail to reject the null hypothesis, since p-value is greaterthan the level of significance(0.0101>0.01)
