Critical Values:
When
774 men from the New Model Army, 226 from the New Model Army, and 226 from the Royalist Army were included in a random sample of the 774 soldiers who took part in the Battle of Preston. Use a 0.05 significance level to test the claim that fewer than one quarter of the soldiers were Royalist

Step 1
It is given that,
Sample proportion,
A researcher claims that fewer than one quarter of the soldiers were Royalist.
Thus, the null and alternative hypothesis are:
Step 2
The standardized test statistic can be calculated as:
The level of significance, =0.05
Form the Z table, the critical value at the level of significance
Conclusion:
Since.
Calculated Statistic
Therefore, it is concluded that fewer than one quarter of the soldiers were Royalist.
