MCQs 2 on "Hypothesis Testing" Statistics

These are MCQs 2 on "Hypothesis Testing" Statistics. Practice MCQs to check your knowledge for Entrance examination like CSIR NET, BINC etc.

1. A hypothesis may be classified as:

• Simple
• Composite
• Null
• All of the above

2. The probability of rejecting the null hypothesis when it is true is called:

• Level of confidence
• Level of significance
• Power of the test
• Difficult to tell

3. The dividing point between the region where the null hypothesis is rejected and the region where it is not rejected is said to be:

• Critical region
• Critical value
• Acceptance region
• Significant region

4. If the critical region is located equally in both sides of the sampling distribution of test-statistic, the test is called:

• One tailed
• Two tailed
• Right tailed
• Left tailed

5. The choice of one-tailed test and two-tailed test depends upon:

• Null hypothesis
• Alternative hypothesis
• None of these
• Composite hypotheses

6. Test of hypothesis Ho: μ = 50 against H1: μ > 50 leads to:

• Left-tailed test
• Right-tailed test
• Two-tailed test
• Difficult to tell

7. Test of hypothesis Ho: μ = 20 against H1: μ < 20 leads to:

• Right one-sided test
• Left one-sided test
• Two-sided test
• All of the above

8. Testing Ho: μ = 25 against H1: μ ≠ 20 leads to:

• Two-tailed test
• Left-tailed test
• Right-tailed test
• Neither (a), (b) and (c)

9. A rule or formula that provides a basis for testing a null hypothesis is called:

• Test-statistic
• Population statistic
• Both of these
• None of the above

10. The range of test statistic-Z is:

• 0 to 1
• -1 to +1
• 0 to ∞
• -∞ to +∞
