Sr. #	Questions	Answers Choice
1	If Ho:π >πo , H1:π <πo and level of significance is=α then Ho will be rejected if	Z < Z=α Z=α/2 < Z Z > Z1-α Z < Z1-α
2	If Ho: μ <μoand H1:μ <μoand level of significance is=α then Ho will be rejected if	Z < Z=α Z < Z=α/2 Z < Z 1-α Z < Z1-α/2
3	Which error is occurred when the defendant were found guilty if, infect the defendant is innocent	type-I type-II no error both a and b
4	The values of test statistic which separate the rejection and non rejection regions for the test are called	simple values critical values parametric values none of these
5	The hypothesis which we are willing to accept when the null hypothesis is rejected is called	simple hypothesis composite hypothesis null hypothesis alternative hypothesis
6	Hypothesis that does not completely specify the underlying population distribution is called	simple hypothesis dual hypothesis composite hypothesis common hypothesis
7	An automobile is driven on the average on more than 1600 kilometers per year, the null hypothesis is	H<sub>o</sub> : μ = 16000 kilometers H<sub>o</sub> : μ ≤  16000 kilometers H<sub>o</sub> : μ < 16000 kilometers H<sub>o</sub> : μ > 16000 kilometers
8	A statistical hypothesis is an assertion or conjecture about the distribution of random variables	one two one or more three
9	If the null hypothesis is false, we many accept it leading to a ----------- decision	true correct wrong none of these
10	A ---------------- error is made by accepting H_o if H₁ is actually true	type - I type - II type - III type - IV
11	The Level of ------------- of test is the maximum probability with which we are willing to a risk of type -I error	correction error significance statistics
12	If we reject Ho when Ho is actually true then it is	type - I error type - II error type - III error type - IV error
13	If critical region is located equally in both tails of the sampling distribution of test statistic, the test is called ------------- test	one tailed two tailed left tailed right tailed
14	A region for which the H_o is rejected is called	acceptance region rejection region critical region both b and c
15	A statistic on the basis of which a decision is made about the hypothesis of interest is called	critical region test statistic parameter rejection region
16	The alternative hypothesis always contains the sign of	equality inequality ratio proportion
17	The hypothesis which is tested for possible rejection is called	common hypothesis null hypothesis alternative hypothesis wrong hypothesis
