An instructor thinks that math majors can write and debug computer programs faster than the math majors. A sample of 18 business majors took an average of 39 minutes and a sample of 12 math majors took an average of 35 minutes. The standard deviations are 9 and 4 respectively. If the value of the test statistic is 1.44, is there evidence to support the claim? Assume that the variables are normally distributed and the population variances are equal. Use alpha= 0:1. Use the p - value approach. 1

Problem 1. Write two computer programs to simulate a Unicode stream cipher that consists of both encryption and decryption algorithms. The encryption program accepts inputs from an existing text file, called “letter.txt.” The encryption program produces an output ciphertext file, called “secret” The decryption program takes “secret” as input and decrypts it into a plaintext, called “message.txt.” - The random “seed” must be known, but be kept secure, by the pseudorandom number generators in both encryption and decryption programs. Note...
