Question # 1

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

Choose an answer

Null hypothesis

Alternative hypothesis

Simple hypothesis

Composite hypothesis

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

Choose an answer

type - I

type - II

type - III

type - IV

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 Ho:π >πo , H1:π <πo and level of significance is=α then Ho will be rejected if

Choose an answer

Z < Z=α

Z=α/2 < Z

Z > Z1-α

Z < Z1-α

Which of the following is not composite hypothesis?

Choose an answer

^{μ < μ}_^

μ > μ₀

μ = μ_o

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

Choose an answer

true

correct

wrong

none of these

A statistical hypothesis is an assertion or conjecture about the distribution of random variables

Choose an answer

one

two

one or more

three

The alternative hypothesis always contains the sign of

Choose an answer

equality

inequality

ratio

proportion

1 -&=nbsp;α is call:

Choose an answer

Confidence coefficient

Power of the test

Size of the test

Level of significance

A region for which the H_o is rejected is called

Choose an answer

acceptance region

rejection region

critical region

both b and c

Hypothesis that does not completely specify the underlying population distribution is called

Choose an answer

simple hypothesis

dual hypothesis

composite hypothesis

common hypothesis

The alternative hypothesis is also called:

Choose an answer

Null hypothesis

Statistical hypothesis

Research hypothesis

Simple hypothesis

A hypothesis that specifies all the value of parameter is called:

Choose an answer

Statistical hypothesis

Simple hypothesis

Composite hypothesis

None of these

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

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

If Ho: μ <μoand H1:μ <μoand level of significance is=α then Ho will be rejected if

Choose an answer
