If the observed outcome is consistent with the position held by the null hypothesis, the hypothesis is accepted. On the other hand, the hypothesis testing by Neyman and Pearson is compared to an alternative hypothesis to make a conclusion about the observed data. The two hypotheses are differenti...
Creating a null hypothesis and an alternative hypothesis, then performing a statistical test of significance are required.A hypothesis test can have left-, right-, or two-tailed distributions. The test statistic’s value, the critical value, and the confidence intervals are used to conclude. ...

Another important term that we will introduce here is the Null hypothesis. The null hypothesis assumes any difference or importance one can see in a data set is by chance. The opposite of the null hypothesis is called the alternative hypothesis. Applying the chi-square to surveys is usually do...

For both two-tailed and one-tailed tests, the null hypothesis is that the mean of the population is equal to the mean of the observed values. In a one-tailed test, the alternative hypothesis is that the mean is smaller (or greater) than the expected mean. In the two-tailed test, ...
population parameters; e.g., a null hypothesis may state that the population mean return is equal to zero. The alternative hypothesis is effectively the opposite of a null hypothesis. Thus, they aremutually exclusive, and only one can be true. However, one of the two hypotheses will always ...
