**Title: Statistical Analysis of Soldier Representation in Historical Battles**

**Critical Values:**
- \( z_{0.005} = 2.575 \)
- \( z_{0.01} = 2.335 \)
- \( z_{0.025} = 1.96 \)

**When Degrees of Freedom (d.f.) = 31:**
- \( t_{0.005} = 2.744 \)
- \( t_{0.01} = 2.453 \)
- \( t_{0.025} = 2.040 \)
- \( t_{0.05} = 1.696 \)
- \( t_{0.1} = 1.282 \)
- \( t_{0.2} = 1.309 \)

**Problem Statement:**

In a random sample of soldiers who fought in the Battle of Preston, 774 soldiers were from the New Model Army, and 226 were from the Royalist Army. Use a 0.05 significance level to test the claim that fewer than one quarter of the soldiers were Royalists.

**Analysis:**

This problem involves a hypothesis test. You are tasked to determine whether the proportion of Royalist soldiers is less than 25% of the total sample. Steps to solve this would include:

1. Define null and alternative hypotheses.
2. Calculate the test statistic.
3. Compare the calculated value with the critical value at a 0.05 significance level.
4. Make a decision to accept or reject the null hypothesis based on the comparison.

Note: If further analysis details, such as the steps of calculation or decision rules, are necessary, consult the corresponding sections on hypothesis testing methodologies.
