Hypothesis

available in the Campus Lake? Population Ecology Experiment Null Hypothesis: The presence of Blue-Green Algae will not have an effect on the Chlamydomonas population. Alternative Hypothesis: The presence of Blue-Green Algae will have an effect on the Chlamydomonas population. Community Ecology Experiment Null Hypothesis: Nitrate concentration will not have an effect on chlorophyll levels in the Campus Lake. Alternative Hypothesis: Nitrate concentration will have an effect on chlorophyll…

My null hypothesis would state that between adult learners taking a course online or in a class setting, there is no difference between midterm tests, on the occasion that both groups take a proctored midterm test. My alternative hypothesis would state that between adult learners taking a course online or in a class setting, there is a difference between midterm tests, on the occasion that both groups take a proctored midterm test. My target population would be first-year students taking college…

her Ted Talk clip, the aquatic ape hypothesis is an interesting take on human evolution. The hypothesis revolved around the idea that human beings evolved from “aquatic apes,” or our early ancestors who called that water their home. This hypothesis takes from the fact that humans share many characteristics with other marine mammals, such as being “naked,” having a layer of fat inside the skin, and having conscious control over breathing. Before this hypothesis, however, another theory for…

Question 1 Null hypothesis The null hypothesis, which is symbolically expressed as H0, is a statement that indicates no difference between a parameter and a specific value or between two parameters. Alternative Hypothesis The alternative hypothesis, which is symbolically expressed as HA or H1, is a statement that indicates the presence of a difference between a parameter and a specific value or between two parameters. Decision Rules On testing the null hypothesis, two main decision rules are…

The efficient market hypothesis (EMH) is widely used to analyse the financial market and security prices. The EMH is efficient if public information is totally reflected by asset prices (Malkiel, 2003, p.59). Malkiel (2003, p.59) implies that information of stock market was exactly shown by security market. In the last ten years, the EMH had significant effect on the financial market. This essay aims to show the three main types of the EMH and analyses if the EMH works in the real market economy…

was inside the black bottle was to understand the basic elements of the scientific inquiry process. We hypothesized that there was a push pin and string inside the unknown bottle—this was based on observations. In order to determine whether our hypothesis was correct or not, we massed out the unknown bottle, an empty bottle, and items that could potentially be inside the bottle. We also put items inside the empty bottle and compared the sound to the unknown bottle. The results showed that there…

differences between these species and using those evidence to support the hypothesis, or vice versa. Base on the researches from Sexual dimorphism and foraging behavior of Emerald Toucanets Aulacorhynchus prasinus in Costa Rica (Riley et al. 2016), using the similar method as this article suggested to find out evidence for supporting the hypothesis. If the experiment rejects the null hypothesis, this means that the hypothesis is true and testable that the fitness of this species is influenced by…

Furthermore, allowed them to generate their hypothesis of experimenting upon the correlation between crime and beauty. Sigall and Ostrove stated two hypothesis, one being that expected beautiful defendants would receive lighter punishments when their beauty was unrelated to the crime (e.g., burglary) compared to an unattractive defendant, or defendant whose beauty was unknown and the second hypothesis being that if the crime involved using one’s beauty to persuade innocent…

to have adequate research, one needs to provide a hypothesis to have validity. He argued that if you don’t come up with a hypothesis before you examine the phenomena, you would not be able to test the evidence fully. He states that if you create your theory after finding evidence, there is no way to test the validity of the theory using that evidence. According to Keynes, he stated that those who provide evidence after coming up with a hypothesis essentially will have more weight placed on it as…

(56 / 100) than those who did not listen to music (42 /100). However, the chi-square test of independence showed no significance. Therefore, the results support, but do not accept hypothesis three: Listening to music while studying will cause students to become less distracted. Also, they do not support or accept hypothesis one: listening to music while studying will cause students to become distracted more often, because the results showed minimal difference between distraction and lack of…
