A statement made about a population for testing purpose is called?

• Statistic

• Hypothesis

• Level of Significance

• Test-Statistic

If the assumed hypothesis is tested for rejection considering it to be true is called?

• Null Hypothesis

• Statistical Hypothesis

• Simple Hypothesis

• Composite Hypothesis

The rejection probability of Null Hypothesis when it is true is called as?

• Level of Confidence

• Level of Significance

• Level of Margin

• Level of Rejection

If the Critical region is evenly distributed then the test is referred as?

• Two tailed

• One tailed

• Three tailed

• Zero tailed

Which of the following is defined as the rule or formula to test a Null Hypothesis?

• Test statistic

• Population statistic

• Variance statistic

• Null statistic

Type 1 error occurs when?

• We reject H₀ if it is True

• We reject H₀ if it is False

• We accept H₀ if it is True

• We accept H₀ if it is False

The probability of Type 1 error is referred as?

• 1-α

• β

• α

• 1-β

The following are methods used to test hypotheses except:

• 
  traditional (computed value) method

• 
  p-value method

• 
  confidence interval method

• 
  survey method

A level of significance of 5% means:

• There's a 5% chance we're wrong

• There's a 5% chance we'll be wrong if we reject the null hypothesis.

• There's a 5% chance we'll be wrong if we fail to reject the null hypothesis

• There's a 5% chance you'll get an A on the test.

Which of the following shows a right-tailed test?

• H₁: µ < 15

• 
  H₁: µ > 15

• 
  

  H₀: µ < 15

• 
  H₀: µ > 15
