How do scientists decide whether or not to reject or accept a hypothesis?
if the hypothesis is proven to be correct or incorrect
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 the differnece between experimental hypothesis and directional hypothesis?
The experimental hypothesis, if stipulated like this, does not imply to be taking any specific direction in its prediction. Hence we will be in a situation were it will only refer to as either, a difference or a correlation only, the experiemntal hypothesis. However, if we decide to give direction to the experimental hypothesis, then we will have to add some information to the stipulation focusing on whether we predict that the difference involved will specifically cause an increase or decrease of the dependent variable(s), the directional hypothesis.
How can you decide which tool to use in a cerain experiment?
it's debend on the hypothesis.
Why might steps in scientific methods be skipped or changed?
Scientists look at their data and decide if the data supports the hypothesis.If the data is exactly the same after many experiments, the hypothesis is supported.If the data does not support the hypothesis, scientist may change the hypothesis or change the experiment .
What are you doing When you decide whether or not the data supports the original hypothesis?
Drawing Conclusions

What does it mean to draw a conclusion?
Scientists decide whether their data supports or refutes their hypothesis or prediction; they look for possible errors...

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 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 is last step of the scientific method?
Demonstrating the truth or falsity of your hypothesis, and then, of course, accepting, rejecting or modifying your original hypothesis as appropriate. Answer The 5th and last step of the scientific method is to DRAW A CONCLUSION based on your experiments. In other words, you decide whether your hypothesis was wrong or right. Also, you could record what you learned from the entire process. Analyze the data and draw conclusions ~ APEX
What is the p-value if 0.01 is the level of significance and the mean is 18688 and the standard deviation is 15500?
In order to solve this you need the null hypothesis value also level of significance only helps you decide whether or not to reject the null hypothesis, is the p-value is above this then you do not reject the null hypothesis, if it is below you reject the null hypothesis Level of significance has nothing to do with the math

Need a hypothesis for how does your power in climbing a flight of stairs compare with the power of a 100 W light bulb?
A hypothesis could be that your power is the same. Or it could be that your power is a million times greater or only one millionth. You decide!A hypothesis could be that your power is the same.
