The frequency of the sinusoidal graph is 3 Hz.
<h3>What is frequency of sinusoidal graph?</h3>
The frequency of a sinusoidal graph is the number of complete waves for every 2π units.
The frequency of the sinusoidal graph is determined by counting the number of complete waves from 
to 
units.
From a sketch of the graph;
Thus, the frequency of the sinusoidal graph is 3 Hz.

There are a lot of ways to test for an hypothesis. There are known five steps of a test of hypothesis through the use of the critical value approach. They are;
- One has to Specify the Null Hypothesis.
- You have to also specify the Alternative Hypothesis.
- Then you set the Significance Level.
- Calculate the Test Statistic and Corresponding P-Value.
- Lastly, Draw a Conclusion.
<h3> The critical value approach?
</h3>
- This is known as a method that involves the determining of the "likelihood" or "unlikelihood" by knowing if or not the observed test statistic is said to be of a more extreme measure than would be expected if the null hypothesis were true.
It often uses the sample data and then there is an assumption if the null hypothesis is true before one can calculate the value of the test statistic.

Answer:
<h3>Plessy v. Ferguson case.</h3>
Explanation:
- The Plessy v. Ferguson case of 1896 ruled out that segregation was constitutional as long as both blacks and whites enjoyed opportunities that were separate but equal.
- However, the Supreme Court's verdict in the Plessy v. Ferguson case of 1896 was challenged by Justice Earl Warren stating that the idea of ‘separate but equal’ in public school was unconstitutional and inherently unequal.
- Thus, Chief Justice Earl Warren issued the Supreme Court’s unanimous decision in Brown v. Board of Education, ruling that racial segregation in public schools violated the "Equal Protection Clause” of the 14th Amendment.
