There are several types of hypothesis testing, primarily categorized into two main types: parametric and non-parametric tests. Parametric tests, such as t-tests and ANOVA, assume that the data follows a specific distribution (usually normal). Non-parametric tests, like the Mann-Whitney U test or the Kruskal-Wallis test, do not rely on these assumptions and are used when the data doesn't meet the criteria for parametric testing. Additionally, hypothesis tests can be classified as one-tailed or two-tailed, depending on whether the hypothesis specifies a direction of the effect or not.

How many types of errors in taking a decision about Ho?
There are two types of errors associated with hypothesis testing. Type I error occurs when the null hypothesis is rejected when it is true. Type II error occurs when the null hypothesis is not rejected when it is false. H0 is referred to as the null hypothesis and Ha (or H1) is referred to as the alternative hypothesis.
What following statement is not part of testing a hypothesis?

Testing of Hypothesis?
A hypothesis is a proposed explanation which scientists test with the available scientific theories. There are four steps to testing a hypothesis; state the hypothesis, formulate an analysis plan, analyze sample data and interpret the results.
What is Hypothesis Testing of Power?
