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
How would you determine the expected frequencies for a chi-square goodness of fit test?
You first decide on a null hypothesis. Expected frequencies are calculated on the basis of the null hypothesis, that is, assuming that the null hypothesis is true.
When a hypothesis is developed what is often designed to test the hypothesis?
An experiment
What do you call the statement that determines if the null hypothesis is rejected?
The hypothesis test.
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
How did czarnowski and triantafyllou test their hypothesis?
Czarnowski and Triantafyllou tested their hypothesis by conducting experiments using numerical simulations and physical models to analyze the dynamic behavior of flexible structures subjected to flowing fluid forces. They observed the behavior of the flexible structures under various conditions to validate their hypothesis regarding the effects of fluid forces on such structures.

Is a hypothesis is a decision based on the results of the experiment.?
No. An hypothesis is an idea put forward to explain an observation. Often you do the experiment to test the hypothesis. The results of the experiment may help you decide whether to discard your hypothesis or to test it further.
What is a hyothcsis?
A hypothesis is an educated guess. In science, when you are given a question or if you want to examine something, you first have to question being asked, which is important to define. Then you need to decide what you think the answer is. This is your HYPOTHESIS. After you have it, you design an experiment to test it. Based on that experiment, decide whether or not your hypothesis is supported by your results. Then you can either adjust your hypothesis or figure out new ways to test it. Science marches on!
What should you do after you form a hypothesis?
test your hypothesis.
How would you determine the expected frequencies for a chi-square goodness of fit test?
You first decide on a null hypothesis. Expected frequencies are calculated on the basis of the null hypothesis, that is, assuming that the null hypothesis is true.
Activity done to test a hypothesis?
A controlled experiment is used to test a hypothesis.
What is the hypothesis in the Taste Test?
The hypothesis is the test that people are taking while eating .
What is a good way to test a hypothesis?
Experimentation is a good way to test a hypothesis.
What does the hypothesis test?
to test a hypothesis means to evaluate the gathered facts with the help of an experiment
What is the symbol for nonparametric hypothesis test?
The symbol for hypothesis test is c2 ( Chi Square)
Would it be possible to test a hypothesis?
If you cannot test it, then hypothesis is probably the wrong word for it.
