Chapter 26, Problem 41E

To determine

To perform chi-square test.

Answer to Problem 41E

There is not sufficient evidence to support the claim that the distribution of outcomes is different among age groups.

Explanation of Solution

Given:

  

The null and alternative hypotheses:

  $H_0$ : The distribution of outcomes is same for all age groups.

  $H_a$ : The distribution of outcomes is differentamong age groups.

Using excel,

  

  ${\chi }^2$ = 5.89 and P-value = 0.1173

Decision: The p-value > 0.05, fail to reject H0.

Conclusion: There is not sufficient evidence to support the claim that the distribution of outcomes is different among age groups.
