A professor of a large math class uses sampling to determine whether grades are curved or now. A two tail hypothesis test example. With R use built-in math and statistics functions find the P-value for a two tailed hypothesis test for a mean.
Choose the level of Significanceα. In a two-tailed test the Ha contains a NOT EQUAL and the test will see if there is a significant difference greater or smaller. In statistics you compare a sample Example. You can check out an equivalent step-by-step guide for other types here. It is used for nondirectional hypothesis like Mean A same as Mean B. A two tailed test.
So if the alternate hypothesis is written with a sign that means that we are going to perform a 2-tailed test because chances are it could be more than 100 or less than 100 which makes it 2-tailed.
You can check out an equivalent step-by-step guide for other types here. It is used when there is a directional hypothesis like Mean A Mean B. Your hypothesis is one-tailed because you are giving no consideration to the possibility that your inferential numbers could be wrong. The output below is from a regression analysis in Stata. A test of a statistical hypothesis where the region of rejection is on both sides of the sampling distribution is called a two-tailed test. In a two-tailed test the Ha contains a NOT EQUAL and the test will see if there is a significant difference greater or smaller.
