Question

Using the accompanying data​ below, perform a​ chi-square test using

α=0.025

to determine if the proportion of​ "Yes" observations differs between Populations A and B.

Observed​ frequencies:

Population	Yes	No
A	22	24
B	18	16

Expected​ frequencies:

Population	Yes	No
A	23	23
B	17	17

What are the null and alternative​ hypotheses?

A.

H0​:

pA≠pB

H1​:

pA=pB

B.

H0​:

pA=pB

H1​:

pA<pB

C.

H0​:

pA=pB

H1​:

pA>pB

D.

H0​:

pA=pB

H1​:

pA≠pBYour answer is correct.

What is the test​ statistic?

χ2=nothing

​(Round to two decimal places as​ needed.)

Answer 1

Chisquare Test For homogeneity

Ho:pA=pB

H1:pA not equal to pB

we Can use Alternative method for finding chisquare

*C- number of coloumn,r-number of row in contingency table
