An experiment
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
The hypothesis test.
scientists test their hypothesis buy making observations or doing research
It depends entirely on what the hypothesis is.
The prediction that he made in designing his experiment was called the scientific method.
Needham manipulated the presence of air in his experimental flasks to test his hypothesis about spontaneous generation of organisms.
Francesco Redi's experiment in the 17th century involved placing meat in jars, some covered with gauze and some left open, to test the idea of spontaneous generation. He demonstrated that maggots did not spontaneously appear on the meat in the covered jars, disproving the prevailing theory at the time.
the answer is B the answer is wroung. just too the test and it's A spontaneous. for the Penn- Fosters test look on pages 142-143 good luck everybody
Scientists use the scientific method, which involves making observations, forming a hypothesis, conducting experiments to test the hypothesis, analyzing the data, and drawing conclusions. In the case of Redi's experiment with rotting meat, Redi observed that maggots appeared on meat left out in the open, so he hypothesized that flies were responsible. He designed an experiment to test his hypothesis by covering the meat with a mesh to prevent flies from landing on it, which led to the conclusion that flies were indeed the source of the maggots.
test your hypothesis.
Louis Pasteur's experiments brought an end to the theory of spontaneous generation, which proposed that living organisms could arise from non-living matter. Pasteur's work demonstrated that microorganisms do not spontaneously generate but instead come from existing cells.
will you test positive for oxycontin and opiates if you are taking both

A controlled experiment is used to test a hypothesis.
The hypothesis is the test that people are taking while eating .
Experimentation is a good way to test a hypothesis.
