Can you reject the null and alternative hypothesis at the same time?
Rejecting or failing to reject the null hypothesis Alternatively, if the significance level is above the cut-off value, we fail to reject the null hypothesis and cannot accept the alternative hypothesis. You should note that you cannot accept the null hypothesis, but only find evidence against it.
Do you have to state the null and alternative hypothesis?
The null is not rejected unless the hypothesis test shows otherwise. The null statement must always contain some form of equality (=, ≤ or ≥) Always write the alternative hypothesis, typically denoted with Ha or H1, using less than, greater than, or not equals symbols, i.e., (≠, >, or <).
What if both null and alternative hypothesis are wrong?
If the hypotheses are incorrect, your conclusion will also be incorrect. The two hypotheses are named the null hypothesis and the alternative hypothesis. In other words, to see if there is enough evidence to reject the null hypothesis. If there is not enough evidence, then we fail to reject the null hypothesis.
Can you have 2 alternative hypothesis?
The alternative hypothesis can be either one-sided or two sided. Use a two-sided alternative hypothesis (also known as a nondirectional hypothesis) to determine whether the population parameter is either greater than or less than the hypothesized value.
What is the purpose of statistical hypothesis discuss null and alternative hypothesis with appropriate examples?
The null and alternative hypotheses are two mutually exclusive statements about a population. A hypothesis test uses sample data to determine whether to reject the null hypothesis.
How do you frame a null hypothesis?
To write a null hypothesis, first start by asking a question. Rephrase that question in a form that assumes no relationship between the variables. In other words, assume a treatment has no effect….Examples of the Null Hypothesis.

Can you have multiple null hypotheses?
Multiple hypothesis testing simply refers to any instance in which more than one null hypothesis is tested simultaneously. While this problem is pervasive throughout all empirical work in economics, we focus on the analysis of data from experiments in economics.
