Question
![**Survey Analysis on Drilling Opinions in California**
A 2010 survey sampled 870 registered voters in California, inquiring about their support or opposition to drilling for oil and natural gas off the coast. Participants were asked: "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 responses were categorized based on whether or not the respondent graduated from college.
**Response Distribution:**
- **College Graduates**
- Support: 150
- Oppose: 180

- **Non-College Graduates**
- Support: 133
- Oppose: 130
- Do not know: 131
- Total: 394
**Questions:**
(a) What percent of college graduates in this sample do not know enough to have an opinion on drilling off the Coast of California?
\[ \text{Percentage: } \boxed{} \]
(b) What percent of non-college graduates in this sample do not know enough to have an opinion on drilling off the Coast of California?
\[ \text{Percentage: } \boxed{} \]
Conduct a hypothesis test to determine if there is strong evidence that the proportion of college graduates who do not have an opinion differs from that of non-college graduates. Perform this test at the 0.05 significance level.
(c) Find the test statistic. The standard error is 0.0313844.
\[ \text{Test Statistic: } \boxed{} \]
(d) Find the positive critical value.
\[ \text{Positive Critical Value: } \boxed{} \]
(e) Find the negative critical value.
\[ \text{Negative Critical Value: } \boxed{} \]
