Question

Education Level and Health Insurance A researcher wishes to see if the number of adults who do not have health insurance is equally distributed among three categories (less than 12 years of education, 12 years of education, more than 12 years of education). A sample of 60 adults who do not have health insurance is selected, and the results are shown. At α=0.10 can it be concluded that the frequencies are not equal? Use the P-value method.

Category	Less than 12 years	12 years	More than 12 years
Frequency	28	22	10

1) State the hypotheses and identify the claim with the correct hypothesis.

: The proportion of adults who do not have health insurance (IS OR IS NOT?) equally distributed among three categories (less than 12 years of education, 12 years of education, more than 12 years of education). (CLAIM OR NOT CLAIM?)

: The proportion of adults who do not have health insurance (IS OR IS NOT?) equally distributed among the three education categories. ▼(CLAIM OR NOT CLAIM?)

2. H0: u1=u2=u3=u4 --------- claim or not?
H1: At least one mean is different from the others--------claim or not?

3. Find the critical value

4. Compute the test value: F =

5. Reject or do not reject the null hypothesis

6. Summarize:
Is there or is there not enough evidence to support claim?
Is there or is there not enough evidence to reject the claim?
