A presidential candidate's aide estimates that, among all college students, the proportion p who intend to vote in the upcoming election is at least 60%. If 127 out of a random sample of 215 college students expressed an intent to vote, can we reject the aide's estimate at the 0.1 level of significance? Perform a one-tailed test. Then fill in the table below.

![### Hypothesis Testing Framework
#### 1. The null hypothesis:
- \( H_0: \) [Input Required]
#### 2. The alternative hypothesis:
- \( H_1: \) [Input Required]
#### 3. The type of test statistic:
- [Dropdown selection is required; options likely include z-test, t-test, chi-square, etc.]
#### 4. The value of the test statistic:
- [Input Required] (Round to at least three decimal places.)
#### 5. The p-value:
- [Input Required] (Round to at least three decimal places.)
#### 6. Decision-making question:
- Can we reject the aide's estimate that the proportion of college students who intend to vote is at least 60%?
- [Yes/No radio button selection required]
#### Additional Interface Features:
- The image includes a selection panel for inserting statistical symbols such as:
- \( \mu, \sigma, p, \bar{x}, s, \hat{p} \)
- Comparison symbols: \( =, \neq, \leq, <, \geq, > \)
These elements suggest an educational focus on guiding the user through the hypothesis testing process, requiring inputs for hypotheses, test statistics, and decision-making based on p-values.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1e80406a-4ff1-4a57-8cbc-804a2a33684b%2Fd956f2bd-2af0-4e44-8b34-30ba8788aeda%2Fz8hyik_processed.jpeg&w=3840&q=75)
