The null hypothesis of this study is that there is no difference in metabolic rate of gold fish before and after increasing environmental temperature. The alternative hypothesis of this study is that metabolic rate of gold fish changes after increasing environmental temperature. Results From a sample size of eight measurements taken from eight different gold fish population, a two-tailed, paired t-test was conducted to determine the relationship between the metabolic rate of gold fish before and
The difference between a hypothesis and a scientific theory is that a hypothesis is a proposed description while a scientific theory is a proven description for something. The difference between a prediction and a hypothesis is that a prediction is a guess at what the results are going to be referring to the proposed hypothesis, while a hypothesis is a proposed explanation where the experiment will be based off of. A testable hypothesis would be useful in scientific experiments because it is testable
Discussion Hypothesis 1: Experiment 1, I accepted my oil hypothesis because the oil formed a thin even layer on top of the water and resumed after I stirred it up with the wooden stick. Vinegar hypothesis: I accepted because the vinegar was only identifiable by smell. Laundry detergent hypothesis: I accepted because the laundry detergent contaminated the water by changing the color to greenish blue and formed bubbles. They all had an effect on either the smell or consistency of the water. The detergent
we can apply these calculations to our results, we formed a null hypothesis relating to the data. The null hypothesis states that there is there is no statistically significant difference between the observed results from our F2 cross and the expected results ratios we received to the ratios we would expect). If there is no statistical significance, we fail to reject the null hypothesis and tentatively accept our previous hypothesis that the autosomal vestigial wing trait will be inherited in a 3:1
As Sekaran states “the null hypothesis is presumed true until statistical evidence, in the form of a hypothesis test, indicates otherwise” (Sekaran, 303). For scenario three, the researcher could state that the null hypothesis could be "everyone is equal in their respective physical speed ability even one of those people may see their athleticism different matched to someone else being sampled." Some may say they are athletic and really only moderately athletic whereas someone may state they are
What hypothesis was tested in Experiment 1? What were the general findings of the experiment? The hypothesis involves a relationship between the racial and ethnic communities of a certain geographic area. That relationship is based on the dialect type of the applicant, and on the success in establishing an appointment to see an apartment. The general findings showed a configuration of a possible discrimination, associated with 3 dialects by geographic area. The experimental hypothesis was supported
was interesting to me because I’ve seen things on the internet that says “Chewing gum helps you remember things” or “chewing gum helps you concentrate” and I wanted to know if it was true. A hypothesis is a prediction statement that you can test, about the relationship between two variables. The hypothesis for this research is that I believe that gum does help you concentrate because it helps you stay alert instead of getting distracted or dozing off. To test this question, there would be two
class, we wondered what evidence we could gather through shell-less eggs so we could show osmosis and diffusion through the egg inner membranes. My hypothesis for the egg in cranberry juice was that the color would change to red. My hypothesis for the egg in La Croix would be that the texture would become rougher and it would become smaller. My hypothesis for the egg in syrup was that the color would become brown and the egg would become larger. I believe with the knowledge I had at the time, that my
Hypothesis Testing Hypothesis testing is basically a process that uses statistical inference to test claims about population parameters. In hypothesis testing we begin by making a tentative assumption about a population parameter. This assumption is called the null hypothesis and is denoted by Ho. We then define another hypothesis, called the alternative hypothesis, which is the opposite of what is stated is the null hypothesis. The alternative hypothesis is denoted by Ha. The hypothesis
Method For Science Fair Question and Hypothesis: Topic: Getting taller from other than DNA and genes The question formulated for this study was, “Can you get taller from other than DNA and genes?” Before research, a hypothesis was made, stating, “Yes, it is possible to get taller from other than DNA and genes.” In order to conduct a valid conclusion for this question, extensive research was executed. Procedure and Research To create that hypothesis 4 main research topics were analyzed: Physics
