# MCQs Hypothesis Testing 1

The post contains MCQs Hypothesis Testing quiz from Statistical Inference for the preparation of exams and different statistical job tests in Government/ Semi-Government or Private Organization sectors. These tests are also helpful in getting admission to different colleges and Universities. The MCQs Hypothesis Testing Quiz will help the learner understand the related concepts and enhance the knowledge. Let us start with Online MCQs Hypothesis Testing with Answers.

1. Which of the following statements describes the significance level?

2. What is the first step when conducting a hypothesis test?

3. What is the null hypothesis of a two-sample t-test?

4. A parameter is a ————- quantity

5. To conclude the null hypothesis, what two concepts are compared?

6. The null hypothesis is a statement that is assumed to be true unless there is convincing evidence to the contrary. The null hypothesis typically assumes that observed data occurs by chance.

7. A data professional conducts a hypothesis test. They discover that their p-value is less than the significance level. What conclusion should they draw?

8. What is the probability of a type II error when $\alpha=0.05$ ?

9. The t distributions are

10. Herbicide A has been used for years in order to kill a particular type of weed. An experiment is to be conducted in order to see whether a new herbicide, Herbicide B, is more effective than Herbicide A. Herbicide A  will continue to be used unless there is sufficient evidence that Herbicide B is more effective. The alternative hypothesis in this problem is

11. Which of the following is a true statement, for comparing the t distributions with standard normal,

12. For t distribution, increasing the sample size, the effect will be on

13. If we reject the null hypothesis, we might be making

14. The _____ typically assumes that observed data does not occur by chance.

15. The critical value of a test statistic is determined from

16. $1 – \alpha$ is the probability of

17. Condition for applying the Central Limit Theorem (CLT) which approximates the sampling distribution of the mean with a normal distribution is?

18. Which of the following is an assumption underlying the use of the t-distributions?

19. What does a two-sample hypothesis test determine?

20. Analysis of Variance (ANOVA) is a test for equality of

Most of the MCQs on this post are covered from Estimate and Estimation, Testing of Hypothesis, Parametric and Non-Parametric tests, etc.
