**Hypothesis Testing for Binomial Experiments**

For one binomial experiment, \( n_1 = 75 \) binomial trials produced \( x_1 = 30 \) successes. For a second independent binomial experiment, \( n_2 = 100 \) binomial trials produced \( x_2 = 50 \) successes. At the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ.

**(a) Compute the pooled probability of success for the two experiments. (Round your answer to three decimal places.)**

\[ \hat{p} = \]

**(b) Check Requirements: What distribution does the sample test statistic follow? Explain.**

- The standard normal. We assume the population distributions are approximately normal.
- The standard normal. The number of trials is sufficiently large.
- The Student's t. We assume the population distributions are approximately normal.
- The Student's t. The number of trials is sufficiently large.

**(c) State the hypotheses.**

- \( H_0: p_1 = p_2; \, H_1: p_1 < p_2 \)
- \( H_0: p_1 = p_2; \, H_1: p_1 > p_2 \)
- \( H_0: p_1 = p_2; \, H_1: p_1 \neq p_2 \)
- \( H_0: p_1 < p_2; \, H_1: p_1 = p_2 \)

**(d) Compute \(\hat{p}_1 - \hat{p}_2\):**

\[ \hat{p}_1 - \hat{p}_2 = \]

Compute the corresponding sample distribution value. (Test the difference \( p_1 - p_2 \). Do not use rounded values. Round your final answer to two decimal places.)

**(e) Find the P-value of the sample test statistic. (Round your answer to four decimal places.)**

\[ \text{P-value} = \]

**(f) Conclude the test.**

- At the \(\alpha = 0.05\) level, we reject the null hypothesis and conclude the data are statistically significant.
- At the \(\alpha = 0.05\) level, we reject the null hypothesis and
