Answer the question B
![**Hypothesis Testing on College Students Working Year-Round**
An education researcher claims that 62% of college students work year-round. In a random sample of 300 college students, 186 say they work year-round. At a significance level of α = 0.05, is there enough evidence to reject the researcher’s claim? Complete parts (a) through (e) below.
**Question (a) - Statement of Hypotheses:**
Select the correct hypothesis from the options given:
A. \( H_0: p > \) [ ]
\( H_a: p \leq \) [ ]
B. \( H_0: p \leq \) [ ]
\( H_a: p > \) [ ]
C. \( H_0: p = 0.62 \) ✓
\( H_a: p \neq 0.62 \)
D. \( H_0: p \neq \) [ ]
\( H_a: p = \) [ ]
E. \( H_0: p \leq \) [ ]
\( H_a: p > \) [ ]
**Question (b) - Critical Values and Rejection Regions:**
Identify the critical value(s) for this test. Use a significance level of α = 0.05.
**\( z_0 = \) [ ]**
**Note:** Ensure to round your answers to two decimal places as needed, using a comma to separate answers if necessary.
