Question # 1

The hypothesis which is tested for possible rejection is called

Choose an answer

common hypothesis

null hypothesis

alternative hypothesis

wrong hypothesis

Level of significance is also called:

Choose an answer

Power of the test

Size of the test

Level of confidence

Confidence coefficient

An example in a two-sided, alternative hypothesis is:

Choose an answer

H₁ :u < 0

H₁ : u > 0

H₁ L u > 0

H₁ : u ≠ 0

A region for which the H_o is rejected is called

Choose an answer

acceptance region

rejection region

critical region

both b and c

A statement about the value of a population parameter is called:

Choose an answer

Null hypothesis

Alternative hypothesis

Simple hypothesis

Composite hypothesis

If critical region is located equally in both tails of the sampling distribution of test statistic, the test is called ------------- test

Choose an answer

one tailed

two tailed

left tailed

right tailed

P(type II error) is equal to:

Choose an answer

α

β

1 - α

1 - β

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

Choose an answer

Composite hypothesis

Null hypothesis

Alternative hypothesis

Simple hypothesis

The values of test statistic which separate the rejection and non rejection regions for the test are called

Choose an answer

simple values

critical values

parametric values

none of these

An automobile is driven on the average on more than 1600 kilometers per year, the null hypothesis is

Choose an answer

H_o : μ = 16000 kilometers

H_o : μ ≤ 16000 kilometers

H_o : μ < 16000 kilometers

H_o : μ > 16000 kilometers

If we reject Ho when Ho is actually true then it is

Choose an answer

type - I error

type - II error

type - III error

type - IV error

A ---------------- error is made by accepting H_o if H₁ is actually true

Choose an answer

type - I

type - II

type - III

type - IV

The alternative hypothesis is also called:

Choose an answer

Null hypothesis

Statistical hypothesis

Research hypothesis

Simple hypothesis

If the null hypothesis is false, we many accept it leading to a ----------- decision

Choose an answer

true

correct

wrong

none of these
