![**The worldwide market share for a web browser was 20.4% in a recent month. Suppose that a sample of 100 random students at a certain university finds that 25 use the browser. Complete parts (a) through (d) below.**
---
**a. At the 0.05 level of significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of 20.4%?**
Determine the null and alternative hypotheses.
- **Option A:** \( H_0: \pi \neq 0.204; \ H_1: \pi = 0.204 \)
- **Option B:** \( H_0: \pi \leq 0.204; \ H_1: \pi > 0.204 \) [Correct Choice]
- **Option C:** \( H_0: \pi = 0.204; \ H_1: \pi < 0.204 \)
- **Option D:** \( H_0: \pi = 0.204; \ H_1: \pi \neq 0.204 \)
**Calculate the test statistic.**
