2 categories minus 1. The degrees of freedom is therefore 1. 8. Find the probability (p) value for 1 degree of freedom in the 0.05 row. Compare this with the chi–square value you calculated in your Lab Notebook. What can you say about the null hypothesis? It is 3.84. Compare this to the chi-square value you calculated earlier. If the chi-square value calculated for your experiment is less than the value of p =

and daylight do not vary. Therefore‚ it is my hypothesis‚ or educated guess‚ that it is our fertilizers that are producing the difference in our crops. I predict‚ or foresee the outcome of my investigation to be that my neighbor’s use of K-gro brand fertilizer results in this abundance of tomatoes that is nearly twice that of my plants. Now for the fun part‚ I will perform an experiment or test‚ to either prove or disprove my theory or hypothesis. I will set up three groups of tomato plants

to my line of sight and then proceeded to measure the moon. I began my observations as the moon rose in the sky and after every hour I would return to the same spot to observe. If my observations are correct‚ it should prove my hypothesis to be true. Hypothesis: We all know the moon does not actually shrink‚ but I do believe that when the moon rises it appears to be much larger than it does when it reaches its highest point in the sky. I think that after the moon rises to its highest point

question that why trees grow in the deserts have small leaves. One hypothesis to that question is that they have needle-like leaves to prevent water loss by giving the sun a smaller area to evaporate water. Based on this hypothesis‚ it is reasonable to predict that if there are two leaves‚ one from ironwood and another one from a tree with bigger leaves‚ Pinus halepensis leaves should contain more water. One way to test this hypothesis is getting same weight of we leaves from both tress and observe

example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which a new variable was added each day therefore changing our hypothesis. We took our 600 mL beaker with the egg in it and allowed the egg to soak overnight in vinegar to dissolve the shell

be successful a hypothesis must be proven right (to whichever extent) or wrong (inaccurate). A hypothesis is a posed statement of‚ IF this were to happen‚ THEN this will result. However it is very important to test these hypotheses under different conditions‚ if you only test your hypotheses under one condition‚ then in certain circumstances it may be proven incorrect. Hypotheses must be tested under new conditions for many different reasons‚ one mainly being if your hypothesis is found true only
