## What are null hypothesis and alternative hypothesis?

Null and alternative hypotheses are used in statistical hypothesis testing. The null hypothesis of a test always predicts no effect or no relationship between variables, while the alternative hypothesis states your research prediction of an effect or relationship.

**What is Htest?**

Objects of class “htest” are lists that contain information about the null and alternative hypotheses, the estimated distribution parameters, the test statistic, the p-value, and (optionally) confidence intervals for distribution parameters.

**What is an example of alternative hypothesis?**

Alternative hypothesis defines there is a statistically important relationship between two variables….Difference Between Null and Alternative Hypothesis.

Null Hypothesis | Alternative Hypothesis |
---|---|

Example: Rohan will win at least Rs.100000 in lucky draw. | Example: Rohan will win less than Rs.100000 in lucky draw. |

### How do you find the alternative hypothesis?

The alternate hypothesis is just an alternative to the null. For example, if your null is “I’m going to win up to $1,000” then your alternate is “I’m going to win $1,000 or more.” Basically, you’re looking at whether there’s enough change (with the alternate hypothesis) to be able to reject the null hypothesis.

**What is t statistic and p-value?**

For each test, the t-value is a way to quantify the difference between the population means and the p-value is the probability of obtaining a t-value with an absolute value at least as large as the one we actually observed in the sample data if the null hypothesis is actually true.

**Is H1 alternative hypothesis?**

The alternative hypothesis, H1 or Ha, is a statistical proposition stating that there is a significant difference between a hypothesized value of a population parameter and its estimated value. When the null hypothesis is tested, a decision is either correct or incorrect.

## What is the meaning of a null hypothesis?

The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.

**What is the t-test null hypothesis?**

A t-test is a statistical test that compares the means of two samples. It is used in hypothesis testing, with a null hypothesis that the difference in group means is zero and an alternate hypothesis that the difference in group means is different from zero.

**Is null hypothesis H0 or H1?**

In hypothesis testing there are two mutually exclusive hypotheses; the Null Hypothesis (H0) and the Alternative Hypothesis (H1).

### What is Ho and H1 hypothesis?

In hypothesis testing there are two mutually exclusive hypotheses; the Null Hypothesis (H0) and the Alternative Hypothesis (H1). One of these is the claim to be tested and based on the sampling results (which infers a similar measurement in the population), the claim will either be supported or not.

**What is alternative hypothesis in research?**

An alternative hypothesis is one in which a difference (or an effect) between two or more variables is [Page 19]anticipated by the researchers; that is, the observed pattern of the data is not due to a chance occurrence.

**What is t-value and p-value?**
