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 .

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.

a. When circuit switching is used, two users can be supported.

b. If two or fewer users are transmitting at the same time, then the 2Mbps link can handle their transmissions, so there will be no queuing delay.

c. The probability that a given user is transmitting is 20%.

d. The probability that all three users are transmitting simultaneously is 0.2 x 0.2 x 0.2 = 0.008, or 0.8%.

What is probability
Probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain. Probability is used to describe the likelihood of a given outcome in a random event.

For example, if you were flipping a fair coin, the probability that it would land on heads would be 1/2, or 0.5. This means that there is a 50% chance that the coin will land on heads.

}

The purpose of this lab is to write a program that will convert a given amount of money in cents into change using the minimum number of coins possible. This is achieved using a greedy algorithm, which means that the program will always choose the highest denomination coin that can be used to make change

Therefore, This program takes the amount of change in cents from the user, then calculates the number of each coin denomination (dollar, half-dollar, quarter, dime, nickel, and penny) required to make that change using the greedy approach described in the problem statement.

To study the effect of the original file size and type on the ratio of the compressed file size to the original file size, you can use a compression utility on your computer to compress different files. Some of the popular compression utilities include WinRAR, 7-Zip, and WinZip.

To start your study, you need to select a set of files of different sizes and types (eg, text files, image files, video files, etc.). Then, use a compression utility to compress each file and compare the compressed size to the original size. You can calculate the compression ratio by dividing the compressed file size by the original file size.

You will probably find that the compression ratio is greatly affected by the type of file being compressed. For example, text files tend to compress very well, often achieving high compression ratios, whereas image and video files tend to compress less efficiently due to the nature of the data they contain. In addition, larger files tend to be compressed less efficiently than smaller files, because there is more data to be compressed and the potential for redundancy is lower.

It's important to note that the exact compression ratio you'll see will depend on the specific compression utility you're using and the specific settings you've selected. However, studying the effect of file size and type on compression ratios is a good way to gain an understanding of the strengths and limitations of different compression algorithms and to make decisions about which compression method to use for different file types.

You can write a do loop that reads integers and computes their sum by using a while loop. The loop should check whether the current integer is zero or the same as the one before it, and break out of the loop if either of those conditions is true. Here is an example of how to write such a loop:

sum = 0

prev = 0

while True:

   num = int(input('Enter an integer: '))

   if num == 0 or num == prev:

       break

   prev = num

   sum += num

print('The sum is', sum)

In this example, the loop will read integers from the user until a zero is entered, or the same value is read twice in a row. If the input is 1 2 3 4 4, then the loop will break out of the loop on the second 4, and the sum will be 14.
