How do you identify alternative hypothesis?
Always write the alternative hypothesis, typically denoted with Ha or H1, using less than, greater than, or not equals symbols, i.e., (≠, >, or <). If we reject the null hypothesis, then we can assume there is enough evidence to support the alternative hypothesis. Never state that a claim is proven true or false.

What is a Type II error quizlet?

What is the best meaning of hypothesis?
