What is null hypothsis?
It is the hypothesis that is presumed true until statistical evidence in the form of a hypothesis test proves it is not true.
Can the alternative hypotheses be true and false?
Yes, the alternative hypothesis can be either true or false, depending on the context of the study or experiment. In hypothesis testing, the alternative hypothesis represents a statement that contradicts the null hypothesis; thus, only one can be true at a given time. If the alternative hypothesis is true, it suggests that there is a significant effect or difference, while if it is false, it indicates that the null hypothesis holds true. Ultimately, statistical tests aim to gather evidence to support one hypothesis over the other.
What is Hypothesis Testing of Type I Error?
Rejecting a true null hypothesis.
What is a hypothesis that has been tested many times and found to be true?
If a hypothesis has been tested many times (using approved experimental methods), and each test has proven the hypothesis to be true, the hypothesis can be taken to be a fact, or truth.
When do we reject a hypothesis?
When we've proven that the hypothesis is false !
A hypothesis is a statement of fact true or false?
A hypothesis is a statement.
True or false If your experiment does not support your hypothesis you should change your data to give support to the hypothesis?
False- The hypothesis is your prediction of what you expect to happen. If the data does not agree with your hypothesis you simply explain why your hypothesis did not come true and possibly investigate variable which would allow your hypothesis to come true.
If your experiment does not support your hypothesis you should change your data to give support to the hypothesis. true or false?
False- The hypothesis is your prediction of what you expect to happen. If the data does not agree with your hypothesis you simply explain why your hypothesis did not come true and possibly investigate variable which would allow your hypothesis to come true.
Can a hypothesis be proven true?
No. A hypothesis is an educated guess, based on observation. Usually, a hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven, but not proven to be true.
If the null hypothesis is true and the researchers do not reject it then a correct decision has been made?
True because the point of the hypothesis test is to figure out the probability of the null hypothesis being true or false. If it is tested and it is true, then you do not reject but you reject it, when it is false.
Is hypothesis a part of conclusion?
in some cases it's true. if it is true in your case, this means your hypothesis was a successful one.

Is A hypothesis is a statement that can be tested true or false?
It is true.
What is the outcome of hypothesis testing?
a. the hypothesis ispartly true but needs to be revised. b. the hypothesis wrong. c. the hypothesis is supported. d. the hypothesis is of no value.
