**Report the critical value for the following hypothesis test question?**

**For a two tale test and right tale test report the positive value.**

**For a left tale test report the negative value.**

A student advisor is interested to see if students finish their studies in more than 4 years. A sample **of 40** students is taken. **18 of them** have finished studies in more than 4 years.

We want to be 90% certain.

Answer:

To find the **critical value** for this hypothesis test, we need to follow the steps for both **two-tailed**, **right-tailed**, and **left-tailed** tests.

### Step 1: Identify the hypothesis
The advisor is interested in seeing if students finish their studies in more than 4 years. So, we will set up the hypothesis for different cases:

- **Null Hypothesis \( H_0 \):** The proportion of students finishing their studies in more than 

Report the critical value for the following hypothesis test question?

For a two tale test and right tale test report the positive value.

For a left tale test report the negative value.

A student advisor is interested to see if students finish their studies in more than 4 years. A sample of 40 students is taken. 18 of them have finished studies in more than 4 years.

We want to be 90% certain.

Learn how to calculate the critical value for a hypothesis test about students' study durations. This problem involves testing whether more than 50% of students finish their studies in more than 4 years, using a sample size of 40 and a confidence level of 90%. Key concepts include Z-tests, critical values, and the Central Limit Theorem.
