the sample size that guarantees all estimates of proportions will meet the margin of error requirements is computed using a planning value of p equal to 0.50 .
what is margin of error?Simply expressed, the margin of error is the potential level of uncertainty in your survey data. It is more likely that the results will deviate from the "actual figures" for the entire population the wider the margin of error. Your results will vary from the actual population value by how many percentage points, as indicated by the margin of error. A 95% confidence interval with a 4% margin of error, for instance, indicates that your statistic will, 95% of the time, be within 4% of the true population figure. Multiplying a key factor (for a specific confidence level) and the population standard deviation yields the calculation for the margin of error.

Perform an experimental study to compare the speed of our AVL tree,
splay tree, and red-black tree implementations for various sequences of
operations
To compare the speed of AVL tree, splay tree, and red-black tree implementations, you can conduct an experimental study with the following steps:
The Steps to followChoose a set of operations (such as insert, delete, search, etc.) that you want to test.
Implement the AVL tree, splay tree, and red-black tree data structures.
Generate test cases that consist of a sequence of operations to perform on the trees. You can generate these test cases in various ways, such as randomly or by specifying specific sequences of operations.
Measure the time it takes for each tree to perform the same sequence of operations. You can use the system clock or a timer function to measure the time.
Repeat the experiment several times to account for any variations in performance due to factors such as system load or other processes running on the computer.
Analyze the results to determine which tree has the best performance for each set of operations. You can also compare the average performance of each tree across multiple test cases.
By conducting this experimental study, you can compare the speed of the three tree implementations and determine which is best suited for specific use cases.

class FibonacciProgression extends Progression {
protected long prev;
public FibonacciProgression(long first, long second) {
super(first);
prev = second - first;
}
protected void advance() {
long temp = prev;
prev = current;
current += temp;

FibonacciProgression fp = new FibonacciProgression(2, 2);
for (int i = 0; i < 8; i++) {
fp.nextValue();
}
System.out.println("The eighth value of the progression is: " + fp.current);

This Java code creates a custom 'FibonacciProgression' class that extends the abstract 'Progression' class. The 'FibonacciProgression' class overrides the 'advance' method to implement the logic for computing the next value in a Fibonacci progression. In the main method, an instance of the 'FibonacciProgression' class is created with the first two values '2' and '2'. The 'nextValue' method is then called 8 times to advance the progression and find the eighth value. The final value is then printed to the console.
