    Type I error, this is an incorrect rejection of a true null hypothesis. By mistakenly rejecting the null hypothesis means erroneously accepting different a hypothesis. So basically, in this scenario or situation, this means that the drug is classified or considered unsafe (but in reality the drug is safe). Also, Type II error is the incorrect failure to reject a false null hypothesis. That is incorrect as well and accepting the null hypothesis. For this scenario, it correlates into that the drug is

  • The Gull Hypothesis

    The null hypothesis of this research is that the gases (helium, nitrogen, argon, and CO2) will have no effect on the football hang time. This study’s alternate hypothesis is if a football is filled with a gas lighter than air (helium and nitrogen), then the football will have a longer hang time; and if a football is filled with a gas heavier than air (argon and CO2), then the football will have a shorter hang time. Since the first experiment results were nullified because of an error in the PSI of

  • Efficient Market Hypothesis Essay

    information is immediately reflected in the prices causing abnormal profit making impossible in the market. The efficient market hypothesis further implies that prices will move randomly that makes prediction of prices extremely difficult. Efficient market hypothesis requires that investors will be rational and have homogenous expectation. Although, efficient market hypothesis came into light after the seminal work of Fama in 1965, Louis Bachelier, a French mathematician, should be considered as the

  • Examples Of Efficient Market Hypothesis

    1341 Words  | 6 Pages

    The Efficient Market Hypothesis The efficient market hypothesis or EMH is one of the fundamental theories of traditional finance. Two economists, Paul A. Samuelson and Eugene F. Fama, independently developed the efficient market hypothesis in modern financial times, but the phenomenon behind the efficient market hypothesis goes as far back as 1565, with evidence of random walks in the market. The efficient market hypothesis simply states that markets are rational in nature

    1) Hypothesis and Null Hypothesis for experiments For the experiment involving the red blood cells, the proposed hypothesis is that if blood cells are placed into a hypotonic solution of distilled water, then the cells will undergo a process called hemolysis where they swell and burst. For this experiment, the null hypothesis is that if blood cells are placed into a hypotonic solution of distilled water, then the cell will not undergo hemolysis. For the experiment involving the elodea plant, the

    preference for oviposition choice. Oviposition is the process of a female insect laying her eyes on plant parts and other materials, which can be influenced by many factors. The bean beetle eggs are opaque and clear, which allowed us to test the hypothesis that C. maculatus prefer the darker red Adzuki beans over the white Black-eyed peas for oviposition choice. Two different colored bean types were used, the red Adzuki beans and the white Black-eyed peas. We placed three female and two male bean

    Pill bugs (Rollie Pollie): The Effect of Isopod Behavior on Wet vs Dry Stimuli Abstract: There are two main purposes for this experiment. First, isopods were observed so that their behavior could be recorded. Second, we exposed the isopods to a wet cotton ball and dry cotton ball, to determine which stimuli the pill bugs (or Rollie pollies) preferred over the other. In the experiment, five different pill bugs were removed from their usual habitat and placed in a choice chamber 1 pill bug at a time

  • Brine Shrimp Lab Report

    My hypothesis for this experiment was not what I expected it to be. Instead of having each section grow in size due to the solution was incorrect. I only had my 1% with solution grow. This is the lowest concentration level I had and my lowest number of brine shrimp in the section without concentration as well. The other sections with my 5% and my 10% concentration ended up with no hatched eggs at all. This could be due to enviornmental reasons. Due to the enviornment brine shrimp usually have

  • The Perils Of Obedience Analysis

    720 Words  | 3 Pages

    “The Perils of Obedience”, written by Stanley Milgram in 1973, explores how her experiment demonstrated people’s affinity to obey orders even if it means someone will get hurt. Milgram is a leading social psychologist who disproved previously considered notions about obedience and authority. Her work demonstrates how obedience trumps morality and gives support for this phenomena with examples from history. By using different participants’ reactions, the author is able to analyze the meaning behind

  • Cray Fish Lab Report

    Our hypothesis was that the crayfish would show metabolic compensation when they are acclimated at different temperature. Our prediction for this experiment was that there would be no difference between oxygen consumption between cold acclimated crayfish and warm acclimated crayfish. Based on our t-test result, the p value was greater than 0.05(p=0.25). Therefore, it supported the prediction that there was no significant difference of the rate of oxygen consumption between warm and cold acclimated

    was to see the behavioral adaptation of the crustaceans to the moist or dry environment and which they preferred. Due to their way of respirating it was hypothesized that they’ll prefer a moist environment over a dry. Results concluded that the hypothesis was denied and not significant. Introduction: Of the diversity of crustaceans, pill bugs pertain to the phylum, Arthropoda; Class, Mandibulata; Order, Isopoda. They became terrestrial through the modification of their respiratory organs. The terrestrial

    method by doing an experiment. I also hope to gain knowledge about the way bridges are structured to hold more weight. Based on my research, I know that the thicker the bridge is, the more weight it will bolster. Knowing this I formed a hypothesis. My hypothesis is the more index cards that the bridge is made out of, the greater amount of pennies it will bolster. Methods Materials: • 6 pink erasers • 3 index cards • 50 pennies • Double sided tape First make 2 balanced bridge supports out of

  • Robinia Invasive Species

    283 Words  | 2 Pages

    Some of the data from our study supports and does not support the prediction. The Robinia pseudoacacia was the only plant species that contradicted our hypothesis. This could be because the R. pseudoacacia is an invasive species in the state of New Jersey. According to invasive species characteristics, they can tolerate many different factors and have a very low tolerance for these factors. They can also spread quickly and have the capabilities of covering large areas. Invasive species are likely

  • Scientific Method

    The scientific method is the process that a person follows when completing experiments. The scientific method consists of observation, hypothesis, experiment, and conclusion. Observation is viewing something interesting and wondering about it. The questions about the observation are what the experiment will be based on. The hypothesis is a statement about the expected outcome. It should be an educated guess based on the experiment and it must be testable. The experiment is comprised of two groups

  • Are Scientists Skeptics Or Rationalists?

    945 Words  | 4 Pages

    Are scientists skeptics, rationalists, or empiricists? It is true that skeptics question ideas, theories, hypothesis, results, and the likes and such - making them search for a valid answer or reason for a certain or particular argument. Rationalists and empiricists on the other hand, although contradictory, have their own qualities that make them relevant towards science. A scientist, to be one, should be a little bit of a skeptic, rationalist, and empiricist. Scientists will need a skeptic's critical
