A hypothesis is a fancy way of saying "guess". So to test a guess, you perform tests, or experiments, and make observations to see if this guess holds. If the experiments are sound (there are no flaws in the setup, you have accounted for all variables or things that can affect the results). And after collecting some data, perhaps repeating the experiment, you can see if the data supports the original hypothesis.

How do you decide whether to use a z test or a t test when testing a hypothesis about a population mean?
You use a z test when you are testing a hypothesis that is using proportions You use a t test when you are testing a hypothesis that is using means
In a two-way ANOVA you can test main hypothesis and one interactive hypothesis?
Not sure about an interactive hypothesis: are you sure you don't mean alternative hypothesis?
When to apply two tailed test in testing hypothesis?
When the alternative hypothesis is non-directional, we use a two-tailed test. Example: H0: mean = 50 Ha : mean not equal to 50 Here is a directional hypothesis that would use a one-tailed test. H0: mean = 40 Ha : mean > 40 or H0: mean = 40 Ha: mean < 40
What does it mean when tests are chi-square based?
A chi-squared test is any statistical hypothesis test in which the sampling distribution of the test statistic is a chi-squared distribution when the null hypothesis is true.
what are the benefits of a two tailed test?
They are used to test hypothesis such as the mean is some value where you do not know if otherwise the mean is less or more.
What does test the hypothesis mean?
to test a hypothesis means to evaluate the gathered facts with the help of an experiment

What should you do after you form a hypothesis?
test your hypothesis.
How do you find the test statistic for a mean hypothesis test?
You can calculate a result that is somehow related to the mean, based on the data available. Provided that you can work out its distribution under the null hypothesis against appropriate alternatives, you have a test statistic.

What does form hypothesis mean?
A hypothesis is a conclusion. To form a hypothesis one would test theories in order to come up with an accurate conclusion.
What does hypothesis really mean in kid words?
it is a question u can test

What hypothesis test would be used to determine the mean weights?

What is a test of hypothesis called?
A hypothesis is any idea used to explain and test a scientific idea. To find if it is true, you need to test it, which you do by running some testing, and it may then be proven.
