A hypothesis specifies only one value or exact value of the population parameter is called .......... hypothesis.

• Simple hypothesis

• Composite hypothesis

• Null hypothesis

• Alternative hypothesis

The hypothesis which complements to the null hypothesis is called ......... hypothesis.

• simple hypothesis

• composite hypothesis

• One tailed hypothesis

• Alternative hypothesis

A region in the sample space in which if the calculated value of the test statistic lies, we reject the null hypothesis then it is called ......... region.

• critical region

• acceptance region

• critical value

• None of these

The decision relating to rejection of null hypothesis H0 when it is true is called ...... error.

• P value

• Type I error

• Type II error

• None of these

The probability of type-I error is known as .......... of a test.

• power

• significance level

• critical value

• None of these

The ......... is the probability of obtaining a test statistic equal to or more extreme than the actual value obtained when null hypothesis is true. 

• power

• size of the test

• P value

• critical value

A p-value greater than 0.05 means:

• Reject the null hypothesis

• Fail to reject the null hypothesis

• The sample size is too small

• There is a significant effect

The critical value in hypothesis testing indicates........

• The value of the test statistic

• The value that the test statistic must exceed to reject the null hypothesis

• The probability of type II error

• The sample size

The population parameter in a hypothesis test is .........

• sample statistic

• Test statistic

• sample mean

• Population mean or proportion

Which of the following is the correct definition of a type II error?

• Rejecting a false null hypothesis
