**Hypothesis Testing Critical Value Approach - 6 - GSB420**

The P-value method converts the standardized test statistic to a probability (P-value) and compares this with the level of significance, whereas the critical value method converts the level of significance to a z-score and compares this with the standardized test statistic. …... QUESTION 1 1. Perform the following hypothesis test using the critical value (traditional) method. Be sure to state the null and alternative hypotheses, identify the critical value, calculate the test statistic, compare the test statistic to the critical value, and state the conclusion.

**hypothesis test using the critical value (traditional) method**

By Alan Anderson . In statistics, a large sample has a size greater than or equal to 30. When you use a large sample to test a hypothesis about a population mean, the resulting two-tailed critical value or values from the standard normal distribution equal how to keep glasses on while playing basketball If you have a P-value less than 5%, which means less than 1 in 20 shot, let's say, you know what, I'm going to reject the null hypothesis. There's less than a 1 in 20 chance of getting that result. Here we got much less than 1 in 20. So this is a very strong indicator that the null hypothesis is incorrect, and the drug definitely has some effect.

## How To Find The Critical Value In A Hypothesis Test

If the critical value is achieved, then the null hypothesis is rejected. A two-tailed test means that the answer should be applicable to both halves of the bell curve, and in a two tailed test the answer must be expressed with both a "+" and "-" sign. For a given alpha value "a," the critical value in a two-tailed test is determined by running the formula (1-a)/2 and then looking up the result

- Critical Values for Statistical Significance ! The z-score needed to reject H 0 is called the critical value for significance. ! The critical value depends on the significance level, which we state as α. ! Each type of alternative hypothesis has it’s own critical values: " One-sided left-tailed test " One-sided right-tailed test " Two-sided test 9 . Critical Values for Statistical
- Moving the critical value provides a trade-o between and A reduction in is always possible by increasing the size of the critical region, but this increases .
- Critical value. In a test of hypothesis, a test statistic is employed to decide whether to reject the null hypothesis or not. If the test statistic falls within a range of values called acceptance region, then the null hypothesis is not rejected.
