![**Title: Testing for Extroversion Among Student Government Leaders**
Are most student government leaders extroverts? According to Myers-Briggs estimates, about 82% of college student government leaders are extroverts. Suppose that a Myers-Briggs personality preference test was given to a random sample of 72 student government leaders attending a large national leadership conference, and that 55 were found to be extroverts. Does this indicate that the population proportion of extroverts among college student government leaders is different (either way) from 82%? Use α = 0.01.
### (a) What is the level of significance?
The level of significance is α = 0.01.
### State the null and alternate hypotheses:
- **\( H_0 \): \( p = 0.82 \); \( H_1 \): \( p \neq 0.82 \) (selected option)**
### Options:
- \( H_0: p = 0.82 \); \( H_1: p < 0.82 \)
- \( H_0: p \neq 0.82 \); \( H_1: p = 0.82 \)
- \( H_0: p = 0.82 \); \( H_1: p > 0.82 \)
### (b) What sampling distribution will you use?
- **The Student's t, since np < 5 and nq ≤ 5. (selected option)**
### Options:
- The standard normal, since np > 5 and nq > 5.
- The standard normal, since np < 5 and nq < 5.
- The Student's t, since np < 5 and nq < 5.
### What is the value of the sample test statistic?
*(Round your answer to two decimal places.)*
