What else can I help you with?
How can a scientist test a hypothesis if he or she cannot do a controlled experiment?
scientists test their hypothesis buy making observations or doing research
When a hypothesis is developed what is often designed to test the hypothesis?
An experiment
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
What do you call the statement that determines if the null hypothesis is rejected?
The hypothesis test.
How is the critical region utilized in hypothesis testing?
When you formulate and test a statistical hypothesis, you compute a test statistic (a numerical value using a formula depending on the test). If the test statistic falls in the critical region, it leads us to reject our hypothesis. If it does not fall in the critical region, we do not reject our hypothesis. The critical region is a numerical interval.
What can scientists do if their test do not support their hypothesis?
Amend or discard the hypothesis
Scientists test a hypothesis by making?
A theory
What do scientists propose and test to arrive at a solution?
a hypothesis
What is the process by which scientists test a hypothesis?
Scientific Method
Do Scientists test a hypothesis by drawing conclusions?
No, scientists do not test a hypothesis by drawing conclusions; instead, they test it through experimentation and observation. A hypothesis is an educated guess that can be tested, and the results of these tests determine whether the hypothesis is supported or refuted. Only after analyzing the data and results can scientists draw conclusions about the validity of the hypothesis. This process is essential for ensuring scientific rigor and reliability.
How do scientists test hypotheses?
Scientists test hypothesis by setting up an experiment. They choose a independent and a dependent variable and test the experiment.

What do scientist do when a hypothesis is not supported by an experiment?
Scientists then state another hypothesis and test it out with another experiment.
What do scientists test?
if your referring to the scientific method, scientists test the dependent variable
In any good experiment the scientists need to what the hypothesis?
Test
Made before scientists can test a hypothesis?
A hypothesis is a proposed explanation for a phenomenon. It is made before scientists conduct experiments or gather data to test whether it is accurate or not. The purpose of testing a hypothesis is to determine if it is supported by evidence and can be considered a valid explanation for the observed phenomenon.
