What is an alternative hypothesis psychology?
Which of the following is an example of alternative hypothesis?
Answer: The alternate hypothesis is just an alternative to the null. For example, if your null is “I’m going to win up to $1000” then your alternate is “I’m going to win more than $1000.” Basically, you’re looking at whether there’s enough change (with the alternate hypothesis) to be able to reject the null hypothesis.

How do you state a null hypothesis?
