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.

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.
Is the statement 'When a hypothesis is tested and shown to be incorrect the experiment is a failure' true or false?
False, your hypothesis has fallacies.
If a hypothesis is proven false something is wrong with the experiment. true false?
False.
If a hypothesis is proven wrong why is it still important?
Generally, creating a hypothesis is a no-win situation. The hypothesis you devise must be provable false. Your data will either prove your hypothesis false or it will fail to prove the hypothesis false. You can never prove a proper hypothesis true. Science does not prove truth, it simply discards the false.
Is research only done after a hypothesis is written?
false
A hypothesis is a statement of fact true or false?
A hypothesis is a statement.
True or false developing a hypothesis is an important contributor to human error?

Why must an hypothesis must be testable?
If a hypothesis does not generate any observational tests, there is nothing that a scientist can do with itRead more: Explain_why_a_hypothesis_must_be_testableANS2:If an hypothesis is not testable, it cannot be provable false. If it cannot be provable false it cannot be supported. If it cannot be supported, it adds nothing to science. An hypothesis is a "no-win" proposition. You need to try to prove it false. That being the case, you either prove it false (lose) or you fail to prove it false (lose). Failing to prove an hypothesis false is the basis for supporting it.
What does it mean for hypothesis to be testable?
The hypothesis must be able to be proved true or false.
What is Hypothesis Testing of Power?
The probability of correctly detecting a false null hypothesis.
