Let's say you're a researcher who wants to study the relationship between the age of a child in foster care and the level of attachment he or she displays towards a foster parent, based on a standardized attachment test. Provide an example of a one-tailed hypothesis for this relationship. Then provide an example of a two-tailed hypothesis for this relationship form a null hypothesis based on the two-tailed hypothesis.
One Tailed:
Two Tailed:
Null:
Now let's say you decide to test the null hypothesis you wrote. You decide to set alpha at .05. You run a stats test and come up with a p-value of .037. Would you retain or reject the null hypothesis?
If you reject the null hypothesis you wrote in the previous question, what does this mean?
