Null hypothesis

Just at the start of the book, A Random Walk Down Wall Street, it seemed to be very interesting, not just saying this because it’s a project. The book is full of information and theories, but it does get harder to follow as I kept reading. Before reading Burton G. Malkiel’s book, A Random Walk Down Wall Street, I knew it would be about the stock market, but I had no Idea it would be full of theories and ideas that make you think harder and more efficiently about the stock market. For this book,…

spectrophotometer. The peroxidase enzyme will be used to test the specific null hypothesis and see the environmental effects on enzyme activity. The first null hypothesis is that “the amount of enzyme does not alter the rate of a reaction” and is covered in the first investigation. A reasoning for this hypothesis may be that the rate of reaction may have to do more with the amount of substrate than the enzyme. The second null hypothesis is that “pH does not influence the rate of an enzyme…

parameter and hypothesis testing. In inferential statistics null hypothesis is a generic statement or certain default position that there is no evidence to establish relationship among two measured phenomena, or when there not any difference among groups. And alternate hypothesis is the claim of researcher which he wants to establish. We use a hypothesis test to make inferences about population when sample data is available. P value in inferential statistics is the probability of null…

not used as a weapon, rather a symbol of distinction. This due to the fact that males generally have a longer rostrum, when compared to the females. (Whiting et al. 2015). This may be because sexual selection favors longer rostrums on males. My hypothesis is that the length of the rostrum on the leaf nosed lizard is an…

Hypothesis 1: In order to see if sex, age and education impact political engagement. It is predicted that interest in politics (REP_05) will be higher in younger people (AGEGR10), and have a high degree of education (DH1GED). The corresponding null hypothesis is that age (AGEGR10), and highest education degree (DH1GED) have no impact on a respondent’s engagement in politics. 2. Hypothesis 2: In order to see if interest in politics is related to…

The null-hypothesis is that there is no significant difference in sales performance between males and females. Before we get to the T-value, Levene’s test for equality of variance must conducted. In SPSS, if Levene test produces a significant figure greater than…

our green light treatment, we fail to reject the null hypothesis and reject our alternative hypothesis because the value was higher than 0.05. Our alternative hypothesis was that red light would be more effective than green light on the rate of photosynthesis and our null hypothesis was that the color of light would not affect the rate of photosynthesis. Without enough evidence to support the alternative hypothesis, we fail to reject the null hypothesis due to a high p-value. Although the…

Discussion Since the experiment is now over I can see whether or not my hypotheses were right or wrong and whether or not the P-Value accepts or rejects the null hypothesis. I predicted that the control group would have the higher average body weight than the experimental rats, in this case my hypothesis was correct. Because the experimental rat was an adolescent it showed different symptoms than the adult rat. If the adult rat had hypothyroidism then they would gain weight, but because the…

Orchis simia is a white-grey and pink colored orchid. Its labellum is shaped like a monkey; complete with four limbs and a tail. It inhabits limestone terrain, grassy and woodland areas. It is spread throughout central to southern Europe, the Mediterranean and North Africa. One third of all orchid species are deceptive, O. simia is no exception; it is nectarless and relies on food deception to attract pollinators. One of O. simia’s known pollinators is the Cidnopus pilosus beetle (Schatz 2006).…

Case Study Synthesis Paper The purpose of this paper is to consolidate many of the facts and methodologies learned and utilized throughout this course. The case study method of research will be used to consolidate learning. Crawford’s (2017), Introduction to Research: Less Fright, More Insight aids in learning the new material. The manual is easy to read and the writing method makes concepts easier to grasp. Using research from a biblical viewpoint helps to broaden my view of research in…
