Question
A 2010 survey asked 838 randomly sampled registered voters in California, "Do you support? Or do you oppose? Drilling for oil and natural gas off the Coast of California? Or do you not know enough to say?" The table below shows the distribution of responses, separated based on whether or not the respondent graduated from college.

|                    | College Grad | Not College Grad |
|--------------------|--------------|------------------|
| Support            | 159          | 131              |
| Oppose             | 176          | 128              |
| Do not know        | 109          | 135              |
| Total              | 444          | 394              |

Conduct a hypothesis test to determine if the data provide strong evidence that the proportion of college graduates who do not have an opinion on this issue is different from that of non-college graduates. Use a significance level of α = 0.08.

Hypotheses:
- \(H_0: \text{prop}_{\text{college grad}} - \text{prop}_{\text{not college grad}} = ? \)
- \(H_A: \text{prop}_{\text{college grad}} - \text{prop}_{\text{not college grad}} \neq ? \)

p-value: ___

Based on this information, we may ___

What type of error could we have made? ___

(Note: The hypothesis test and the blanks are intended for educational practice in hypothesis testing.)
