Efficient-market hypothesis

Overall, I rate this article as a 4 out of 5. It is very well organized, presents samples and comparisons and is very well written. The only thing, I would change in this article would be the organization of the topics. For Example, The hypotheses, methods and procedures were placed at the end with the results. I believe the hypotheses, methods, and procedures would have been more effective placed at the beginning of the article before the presentation of the data that is broken up into sections…

After collection of enough spectrum sensing results from each secondary user by the FC as above, relation is determined in the spectrum sensing results of each SU to identify both OMU and ROMU with the abnormal sensing reports to the fusion centre using the following steps. Variation in the Sensing results In the first step, FC measure the differences in the sensing results provided by each individual SU with all other SUs, during each sensing interval from initial to N_0 interval. Here sensing…

After the data was collected it was formulated into 4 tables relating to Alpha Amplitude, Alpha Frequency, Beta Amplitude and Beta Frequency, the tables can be found in the appendix section below. The tables contain ID numbers to identify the volunteers as well as columns to show the amplitude (μV)/frequency (Hz) of alpha and beta during the four periods of no music (NM1, NM2, NM3, NM4),CL, CH, RL and RH. The percentage increase for all the different types of music compared to no music was…

Question 1 (i) Mean: ‘’The sum of a series of measurements (or numbers) divided by the number of those measurements.’’ (Open University,2015: S104 Exploring Science Glossary, Milton Keynes, The Open University). Scientific Notation: ‘’ A notation that represents any number by expressing it as a number that is equal to or greater than 1 but less than 10, multiplied by a simple power of ten where the index may be positive or negative. Thus, 1.30 × 103 is in scientific notation (because 1.30 is…

Discussion The T-test from the class supported our hypothesis by showing that Sulfuric Acid diffused significantly faster than phenol red at both temperatures (Fig 1). We can say that our hypothesis for experiment one is supported under certain conditions. The rest of the data in our charts supports our hypothesis as well. However it is not well supported. The rest of the test results were inconsistent with the null hypothesis. The error bars from the class data show a possible cause of…

whether or not the means differ significantly. From a t-test a null hypothesis can be determined. The null hypothesis for this study is the mean number of species found within the lawn and the prairie are the same, while the alternative hypothesis states that the mean number of species found within the lawn and the prairie are not equal. As determined by the p-value of 0.007434, for a two-tail t-test, one should reject the null hypothesis and accept…

However, even though this is the population from which a sample was taken for the research, it may be assumed that ultimately the goal of the study is to define the population as all workers in Taiwan, for purposes of extrapolation of the data. Additionally, only respondents holding a full-time job were selected for the analysis in order to highlight the potential effects of work/family conflict (Lu et al., 2011). Description of Data and Descriptive Statistics A wide variety of data was…

reject the null hypothesis that the mean of D3 is not significantly different than the mean of D1. Consequently, another two-sample Pooled t test was used to test the hypothesis that the mean delivery speed of deliveryman 4 (D4) is not significantly different from mean delivery speed of deliveryman 1 (D1) at a 5% level of significance and 39 degrees of freedom. There was sufficient statistical evidence at the 5% significance level (t=-5.436 and tcrit=-2.023) to reject the null hypothesis that…
