Although we found that the duckweed grows faster in the NP solution‚ rather than the creek water they do indeed have relatively the same mean. Overall our results supports our hypothesis. This also makes us question what kinds of factors are affecting the creek water to kill off the duckweed. Duckweed also is known to stop the growth of algae‚ but in our experiment we ended up having algae grow in some of the wells filled with creek

Chicago‚ Illinois has numbers that exceed more than 93‚000 individuals that are homeless and out of those there is close to 20‚000 that also suffer with a mental illness. In addressing the link between mental illness and homelessness it is clear that the numbers are large due to lack of medical care and the de-institutionalization from the 1960’s. In an attempt to

All of the plants in the groups with 5 seeds at least grew. This indicates that dependent variables such as competition and the environment itself has an influence on how a plant grows and develops. If the T-Stat>T-Critical‚ then we reject the null hypothesis and choose the alternative. The only one we actually accept the null hypothesis are the Leaves

The criteria for a hypothesis-based scientific study involves a few steps that should be followed in order. First‚ an observation is made and then a question should be posed about the observation that can be tested and possibly proved false. Next‚ we can make a hypothesis or educated guess about the result cause of the problem. We can then make a prediction on what may fix the issue. The final step would be to test our prediction to find the conclusion. The difference between a scientific based

Hypothesis Testing The sole purpose of hypothesis testing is to determine whether or not research that has been collected is proved or disproved; usually allowing up to a 5% error factor. By using this 5% margin of error a researcher can consider the question of research being conducted is proven. There are five steps to be followed in doing hypotheses testing. The steps are: developing the research question‚ specifying between null and alternative hypotheses‚ calculating the statistic‚ computing

Hypothesis Testing and Nursing Hypothesis testing is a method of making decisions using data from scientific study. In statistics‚ a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone‚ according to pre-determined threshold probability‚ the significance level. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect based on how
