The probability that the test statistic will fall in the rejection region (aka the CRITICAL region) if the null hypothesis is true is the LEVEL OF SIGNIFICANCE of the test, which we denote as alpha. - this is set by the researcher... Region of Rejection. For a hypothesis test, a researcher collects sample data. From the sample data, the researcher computes a test statistic. If the statistic falls within a specified range of values, the researcher rejects the null hypothesis . The range of values that leads the researcher to reject the null hypothesis is called the region of rejection. For example, a researcher might

Rejection Region: probability as computed by Excel Example 1: Two procedures to determine the amylase in human body fluids were studied. The "original" method is considered to be an acceptable standard method, while the "new" method uses a smaller volume of water, making it more convenient as well as more economical.

## How To Find Rejection Region With Alpha

### The level of significance is the area of the shaded region, and is called the rejection region. If a two-tailed test is done, that sum of the areas of the rejection region is the level of significance. An inverse distribution function on the value $\alpha$ (or for two-tailed tests, on the value $\alpha/2$) is used to obtain the critical value(s).

- 29/05/2013Â Â· Best Answer: a) In case of a right tailed test the rejection region is represented by the area in the extreme right tail of the normal curve. At alpha = 0.05, the rejection region is 0.0500 in the extreme right tail. P(Z > 1.645) = 0.0500 because the critical value of z corresponding to alpha = 0.05
- At \(\alpha = 0.05\), we conclude that, on average, the bottom zinc concentration is higher than the surface zinc concentration. Using Minitab to Perform a Paired t -Test You can used a paired t -test in Minitab to perform the test.

- In general we reject the null hypothesis at level Î± (alpha) if the p-value < Î± and do not reject the null hypothesis at level Î± if the p-value >= Î±. [A common choice of Î± is 0.05].
