The five-step processes for hypothesis testing are the following. Step1. Specify the null hypothesis H0 and alternative hypothesis H1. The null hypothesis is the hypothesis that the researcher formulates and proceeds to test. If the null hypothesis is rejected after the test‚ the hypothesis to be accepted is called the alternative hypothesis. For example if the researcher wants to compare the average value generated by two different procedures the null hypothesis to be tested is [pic] and

The two visual systems hypothesis talks about the processing of the visual information in two different routes in the brain (van Polanen & Davare‚ 2015). This idea was first introduced in 1982 when Leslie Ungerleider and Mortimer Mishkin described experiments that distinguished two streams that served different functions(Melvyn A. Goodale‚ 1998). They used the method know as ablation or also called lesioning. Using both recordings from neurons and ablation‚ they found that properties of the ventral

AUTHOR: CHARLES EKWE RUO “In an efficient market‚ security (example shares) prices rationally reflect available information” (Arnold 2005‚ p.684).

statistical test did not support the hypothesis. The statistical test proves that the null hypothesis can be accepted regarding temperature impacting weight. However‚ we accept the hypothesis regarding conductivity. The test shows that the conductivity of a cell submerged in a solution can be altered with changes in temperature as the independent variable. However‚ the test shows that we accept the null hypothesis for weight change because weight is not impacted by temperature. The statistical test used

Definition of ’Efficient Market Hypothesis - EMH’ An investment theory that states it is impossible to "beat the market" because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information. According to the EMH‚ stocks always trade at their fair value on stock exchanges‚ making it impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices. As such‚ it should be impossible to outperform the overall market through
