(a)
Answer to Problem 21.1AYK
P-value
Explanation of Solution
Given:
Two titled downward
Concept used:
Formula
Degree of freedom
Significance level
Calculation:
Since the sample size are large.
The condition for the two samples
Applying chi-square test of independence
Draw the table

Chi-square
Chi-square
Degree of freedom
P-value
The p-value of the test is
Since p-value is greater than
The result significant at
So, the null hypothesis is fail to reject.
(b)
To explain:
Thenull and alternative hypothesis of the given data.
