Question

I need help with all parts of this question 2

A random sample of \( n = 1,200 \) observations from a binomial population produced \( x = 694 \) successes. You wish to show that \( p \) differs from \( 0.6 \).

**State the null and alternative hypothesis.**
- \( H_0: p < 0.6 \) versus \( H_a: p > 0.6 \)
- \( H_0: p = 0.6 \) versus \( H_a: p > 0.6 \)
- \( H_0: p \neq 0.6 \) versus \( H_a: p = 0.6 \)
- \( H_0: p = 0.6 \) versus \( H_a: p < 0.6 \)
- \( H_0: p = 0.6 \) versus \( H_a: p \neq 0.6 \)

**Calculate the appropriate test statistic.** (Round your answer to two decimal places.)
\[ z = \]

**Provide an \( \alpha = 0.05 \) rejection region.** (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.)
\[ z > \]
\[ z < \]

**State your conclusion.**
- \( H_0 \) is rejected. There is insufficient evidence to indicate that \( p \) differs from 0.6.
- \( H_0 \) is not rejected. There is sufficient evidence to indicate that \( p \) differs from 0.6.
- \( H_0 \) is not rejected. There is insufficient evidence to indicate that \( p \) differs from 0.6.
- \( H_0 \) is rejected. There is sufficient evidence to indicate that \( p \) differs from 0.6.
