Which is the best definition of a hypothesis?
A hypothesis is a function that best describes the target in supervised machine learning. The hypothesis that an algorithm would come up depends upon the data and also depends upon the restrictions and bias that we have imposed on the data.

How do you test a hypothesis in statistics?
To test a statistical hypothesis, you take a sample, collect data, form a statistic, standardize it to form a test statistic, and decide whether the test statistic refutes the claim. The following table lays out the important details for hypothesis tests.
When to reject the null hypothesis in a hypothesis test?
You can also use these critical z *-values for hypothesis tests in which the test statistic follows a Z -distribution. If the absolute value of the test statistic is greater than the corresponding z *-value, then reject the null hypothesis.
