Chapter 26, Problem 42E

To determine

To perform chi-square test.

Answer to Problem 42E

There issufficient evidence to support the claim that the distribution of education level is different among age groups.

Explanation of Solution

Given:

  

The null and alternative hypotheses:

  $H_0$ : The distribution of education level is same for all age group.

  $H_a$ : The distribution of education level is different among age groups.

Using excel,

  

  ${\chi }^2$ = 178.45 and P-value = 0

Decision: The p-value < 0.05, reject H0.

Conclusion: There issufficient evidence to support the claim that the distribution of education level is different among age groups.
