Problem 1)

Try creating 100 normally disributed random numbers with an average of 10 and standard deviation of 1. How close is the average to 10? How close is the standard deviation to 1?

Problem 2)

Try creating 100 normally disributed random numbers with a true average of 10 and true standard deviation of 1. What is the confidence interval for the measured average? Is it higher or lower than the confidence interval for 20 samples?

1.) Generate an array of 10 random numbers between 1 - 100 2.) Copy the array to a temp array 3.) Call each of the methods to sort (bubble, selection, insertion, quick, merge), passing it the array 4.) In-between the calls, you are going to refresh the array to the original numbers. 5.) Inside of each sorting method, you are going to obtain the nanoseconds time, before and after the method Subtract the before time from the after time to...

1. Lets start by creating a traditional random password composed of numbers, letters, and a few special characters. letters = "abcdefghijklmnopqrstuvwxyz" caps = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" numbers = "1234567890" # Make an 8 letter password by combining characters from the three strings 2. Next you follow the XKCD model of selecting four random words and concatenating them together to for our password. nouns = ['tissue', 'processor', 'headquarters', 'favorite', 'cure', 'ideology', 'funeral', 'engine', 'isolation', 'perception', 'hat', 'mountain', 'session', 'case', 'legislature', 'consent', 'spread', 'shot',...

Write C++ program (submit the .cpp,.h, .sln and .vcxproj files) Problem 1. Generate 100 random numbers of the values 1-20 in an input.txt. Now create a binary search tree using the numbers of the sequence. The tree set should not have any nodes with same values and all repeated numbers of the random sequence must be stored in the node as a counter variable. For example, if there are five 20s’ in the random sequence then the tree node having...
