QUANTITATIVE TECHNIQUES

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

• Level of Confidence
• Level of Significance
• Level of Rejection
• Level of Margin

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

• Two tail
• One tail right side
• One tail left side
• Zero tail

Consider a hypothesis where H0 where µ > = 23 against H1 where µ < 23. The test is?

• Right
• Left
• Both
• None

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

If a hypothesis is rejected at the 0.025 level of significance, it:

• Must Be Rejected At Any Level
• Must Be Rejected At The 0.01 Level
• Must Not Be Rejected At The 0.01 Level
• May Or May Not Be Rejected At The 0.01 Level

In a one-tail test for the population mean, if the null hypothesis is not rejected when the alternative hypothesis is true, then:

• A Type I Error Is Committed
• A Type II Error Is Committed
• A Correct Decision Is Made
• A Two-Tail Test Should Be Used Instead Of A One-Tail Test

In hypothesis testing, what level of significance would be most appropriate to choose if you knew that making a Type I error would be more costly than making a Type II error?

• 0.005
• 0.025
• 0.05
• 0.1

Suppose that we reject a null hypothesis at the 5% level of significance. For which of the following levels of significance do we also reject the null hypothesis?

• 0.025
• 0.06
• 0.04
• 0.03

In hypothesis testing, the hypothesis which is tentatively assumed to be true is called the

• Correct Hypothesis
• Null Hypothesis
• Alternate hypothesis
• Level of Significance

The maximum probability of a Type I error that the decision maker will tolerate is called the

• critical value
• decision value
• Level of Significance
• probability value
