Question: A null hypothesis is a statement about a population parameter, an alternative hypothesis is a statement that contradicts the null hypothesis. A test statistic is

A null hypothesis is a statement about a population parameter, an alternative hypothesis is a statement that contradicts the null hypothesis. A test statistic is a value calculated from the sample data that is used to test the null hypothesis. Critical region is a set values of the test statistic. Signifigance level is the probability of rejecting the null hypothesis. Critical value is the boundary of the critical region. P value is the probability of obtaining a test statistic. 2: A two tailed test is used when the alternative hypothesis is that the population parameter is different from the null hypothesis while the right tail test is used when the alternative hypothesis is that the population parameter is greater than the null hypothesis value that was given. 3: An example of how hypothesis testing could be used in one profession such as in the medical field includes a medical researcher who is wanting to test the effectivness of a new drug
