Assume that a station X wants to send 15 packets of data to station Y using TCP Tahoe. Assuming that:1) The size of each packet sent is 1000 Bytes (ignore all the headers from layers below).2) Station X chooses 43 as an initial sequence number.3) Station Y chooses 2 as an initial sequence number.4) The data of the first packet is included in the final packet of the handshake process.5) The sender window size is 5 packets.6) The receiver window...
Part 1 You have been asked to estimate the mean number of seals killed by a polar bear in one year. The Polar Bear tab of this spreadsheeet contains a random sample of polar bears and their annual seal kills 1. What is your best estimate for the population mean? 2. If you are going to construct at 95% confidence interval, what is the appropriate critical value ("? 13. What is the 95% confidence interval for the population mean? Part...
check my answers for Networking I came up with these answers, can check my answers Question 1: General What data rate is needed to transmit an uncompressed 4" x 6" photograph every second with a resolution of 1200 dots per inch and 24 bits per dot (pixel)? 691,200 kb/s 28.8 kb/s 8.29 Mb/s 829 Mb/s Question 2: Layering "Layering" is commonly used in computer networks because (check all that apply): -It forces all network software to be written in ‘C’....
Using Python Version 1. Write a program that uses a "while" loop to print the first 10 positive integers and to compute their sum. Print the sum after it is computed. Do the same with a "for" loop. Version 2. Write a program to approximate the square root of a number. Recall that the square root of a number x is a number r such that r*r = x. Newton discovered that if one initial estimate of r is z...
1) Out of 100 people sampled, 60 preferred Candidate A. Based on this, estimate what proportion of the voting population (pp) prefers Candidate A. Use a 99% confidence level, and give your answers as decimals, to three places. _____ < P < ______ 2) You work for a marketing firm that has a large client in the automobile industry. You have been asked to estimate the proportion of households in Chicago that have two or more vehicles. You have been...
1) You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=20.5σ=20.5. You would like to be 90% confident that your esimate is within 10 of the true population mean. How large of a sample size is required? n = Use a critical value accurate to three decimal places, and do not round mid-calculation — this is important for the system to be able to give hints...
In constructing a 90% confidence level estimate of the mean when the population standard deviation (σ) is known what will be your z score used in the formula? HINT: Be sure to review page 236 "Finding Z scores from Known Areas - Special Cases" and Tabel A-2. If you identified it as 1.64 contact me in the DB and I will provide partial credit. Please see my lecture "CIE of the mean z and t examples 2015" as to an...

Use
either the P-value method or the traditional method of testing
hypotheses. Company A uses a new production method to manufacture
aircraft altimeters. A simple random sample of new altimeters
resulted in errors listed below. Use a 0.05 level of significance
to test the claim that the new production method has errors with a
standard deviation greater than 32.2 ft which was the standard
deviation for the old production method. If it appears that the
standard deviation is greater does...
