## Which hypothesis can be tentatively assumed to be true?

First, we make a tentative assumption about the distribution or parameter. This assumption is known as the null hypothesis, and it is denoted H0. The null hypothesis is replaced by H0. An alternative hypothesis (denoted Ha) is then defined.

** Can a hypothesis be tentatively assumed **

The hypothesis was tentatively accepted to be true during the hypothesis testing process. Ho is not true, and Ho was accepted.

** When testing a hypothesis, the hypothesis that is presumed to be true is: **

C. This symbol is used to identify the hypothesis to be tested. It is also known as the null hypothesis. The null hypothesis, as explained below, is presumed to be true unless strong evidence is presented. This is similar to the assumption that a person is innocent until proven guilty.

### What are the assumptions in hypothesis testing?

Statistical hypothesis test requires several assumptions. These assumptions include the level of measurement, sampling method, shape of the population, and sample size.

**How can you tell if a hypothesis has one tail or two? **

A one-tailed test contains the whole 5% of your alpha level in one tail. It can be either the left or right tail. Two-tailed tests split your alpha level in half (see the image to left). Let’s assume you have a standard alpha level (5%) of 0.5. Two-tailed tests will have the same alpha level (2.5%) in each tail.

** What does it mean to have one and two tails? **

The Basics of a One Tail Hypothesis Testing is used to test whether a claim is true, given a population parameter. Two-tailed tests are those that show whether the average of the sample is significantly higher than or significantly lower than the population’s mean.
