Answer:
Option A is correct
Step-by-step explanation:
- In carrying out a two sample t-test, we must first of all state the null and alternative hypothesis and identify the claim.
- The next thing we will do is to identify the level of significance of the test. It's usually denoted as α.
- The next step would be to find the critical values and identify the rejection region. The critical value is the value that a test statistic must exceed that will make the the null hypothesis to be rejected. This will enable us find out the region where we can reject the null hypothesis.
-The next step is to find the standardized test statistic which is the t-score..
- Next step would be to make a decision on the claim from when the p-value from the t-score is compared with the level of significance and checked with the rejection region.
The only option that follows this order is option A
Option A is the correct option
T-test:
The t-test is any statistical hypothesis test in which the test statistic follows a Student’s t-distribution under the null hypothesis.
For the test first state, a hypothesis then identifies the claims specify the provision of a level of significance calculated the degree of freedom .
Then statistics find the rejection region find standardized statistics and finally, interpret the claim
